Electric Literature of C8H12Cl2Pt. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Platinum(II) Complexes with Bis(pyrazolyl)borate Ligands: Increased Molecular Rigidity for Bidentate Ligand Systems. Author is Soellner, Johannes; Pinter, Piermaria; Stipurin, Sergej; Strassner, Thomas.

The structural motif of platinum(II) complexes bearing cyclometalating N-heterocyclic carbene ligands can be used to design deep-blue phosphors for application in organic light-emitting diodes. However, the photophys. properties of the resulting mols. are also highly dependent on the auxiliary ligand. These often allow mol. deformations in the excited state which contribute to non-radiative decay processes that diminish the attainable quantum yield. The use of bis(pyrazolyl)borate-based auxiliary ligands enforces a high mol. rigidity due to their unique geometry. The steric crowding in the coordination sphere inhibits deformation processes and results in highly efficient deep-blue platinum(II) emitters with CIE coordinates below (0.15; 0.15).

Application of 12080-32-9. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Multifunctional Pt(II)-Based Metallo-Supramolecular Polymer with Carboxylic Acid Groups: Electrochemical, Mechanochemical, Humidity, and pH Response. Author is Chakraborty, Chanchal; Rana, Utpal; Moriyama, Satoshi; Higuchi, Masayoshi.

We report multifunctional Pt(II)-based metallo-supramol. polymer with carboxylic acid groups (polyPtC). The polymer showed multi-stimuli-responsive emission to electrochem. redox, mech. force, humidity, and pH. It also exhibited humidity-responsive ionic conductivity Furthermore, it displayed electrofluorochromism. The emission switching between the two transition states (3MLCT/3LLCT and 3MMLCT) was based on the reversible changes of the interchain Pt-Pt interaction in polyPtC, which was caused by the secondary interaction or the crystalline-amorphous transition. The ionic conductivity of polyPtC was responsible for the humidity and the real-time humidity sensor with the polymer film was demonstrated on interdigitated Pt-electrodes. A solid-state electrochromic device with the polymer film was successfully fabricated to show reversible yellow-to-black electrochromism. In addition, it was revealed by the electrofluorochromic study that the pristine 3MLCT/3LLCT emission was quenched in the electrochem. reduced state (the black state), because the radical anion species of the ligand (tpy·-) generated at the neg. potential caused the repulsion among the polymer chains, expanded the Pt-Pt distance, and prevented the emission.

We demonstrate an advanced chem. vapor deposition (CVD) approach in which the addition of Pt-containing hydrocarbons to ferrocene allows the nucleation of a novel carbon-foam material completely filled with elemental Fe and Pt crystal-phases. These phases are then found to alloy into tetragonal FePt and cubic FePt3 in specific annealing conditions. A dependence of the FePt nucleation on the Ar/H2 flow rate is reported. In addition, high pressure (5 GPa) experiments are found to favor the formation of a single FePt3 encapsulated phase together with the nucleation of C-O rich carbon layers in the foam surface.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Angewandte Chemie, International Edition called [n]-Cyclo-9,9-dibutyl-2,7-fluorene (n=4, 5): Nanoring Size Influence in Carbon-Bridged Cyclo-para-phenylenes, Author is Sicard, Lambert; Lucas, Fabien; Jeannin, Olivier; Bouit, Pierre-Antoine; Rault-Berthelot, Joelle; Quinton, Cassandre; Poriel, Cyril, which mentions a compound: 12080-32-9, SMILESS is C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-], Molecular C8H12Cl2Pt, Related Products of 12080-32-9.

For the last ten years, ring-shaped π-conjugated macrocycles possessing radially directed π-orbitals have been subject to intense research. The electronic properties of these rings are deeply dependent on their size. However, most studies involve the flagship family of nanorings: the cyclo-para-phenylenes. We report herein the synthesis and study of the first examples of cyclofluorenes possessing five constituting fluorene units. The structural, optical and electrochem. properties were elucidated by X-ray crystallog., UV-vis absorption and fluorescence spectroscopy, and cyclic voltammetry. By comparison with a shorter analog, we show how the electronic properties of [5]-cyclofluorenes are drastically different from those of [4]-cyclofluorenes, highlighting the key role played by the ring size in the cyclofluorene family.

A platform for investigating the impact of π-extension in benzannulated, anionic pincer-type N^N-^N-coordinating amido ligands and their Pt(II) complexes is presented. Based on bis(8-quinolinyl)amine, sym. and asym. proligands bearing quinoline or π-extended phenanthridine (3,4-benzoquinoline) units are reported, along with their red-emitting, phosphorescent Pt(II) complexes of the form (N^N-^N)PtCl. Comparing the photophys. properties of complexes of (quinolinyl)amido ligands with those of π-extended (phenanthridinyl)amido analogs revealed a counterintuitive impact of site-selective benzannulation. Contrary to conventional assumptions regarding π-extension, and in contrast to isoenergetic lowest energy absorption bands and a red shift in fluorescence from the organic proligands, a blue shift of nearly 40 nm in the emission wavelength is observed for Pt(II) complexes with more extended bis(phenanthridinyl) ligand π-systems. Comparing the ground state and triplet excited state structures optimized from d. functional theory (DFT) and time-dependent-DFT calculations, we trace this effect to a greater rigidity of the benzannulated complexes, resulting in a higher energy emissive triplet state, rather than to a significant perturbation of orbital energies caused by π-extension. A counterintuitive impact of π-extension on luminescence from deep red emitting Pt(II) complexes of benzannulated, anionic pincer-type N^N-^N-coordinating amido ligands is reported. Contrary to conventional assumptions, isoenergetic lowest energy absorption bands and a red shift in fluorescence from the organic proligands, a blue shift in the emission wavelength is observed for Pt(II) complexes with more extended bis(phenanthridinyl) π-systems, traced to a greater rigidity of the benzannulated complexes and a higher energy triplet state.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Square Planar Nucleophilic and Radical Pt(II) Carbenes.Application In Synthesis of Dichloro(1,5-cyclooctadiene)platinum(II).

A square planar platinum(II) carbene complex [{PC(sp2)P}HPt(PMe3)] ([PC(sp2)P]H = (bis[2-(di-iso-propylphosphino)phenyl]methylene)) was synthesized through the dehydrohalogenation of [{PC(sp3)HP}HPtCl] in a microwave reactor. The tert-Bu substituted analog, [{PC(sp2)P}tBuPt(PMe3)] ([PC(sp2)P]tBu = bis[2-(di-iso-propylphosphino)-4-tert-butylphenyl]methylene), was synthesized via an analogous route. The nucleophilic nature of the carbene carbon was confirmed through DFT calculations and reactivity with HCl. Addnl., [{PC(sp2)P}HPt(PMe3)] was treated with 0.5 equiv of I2 to generate a paramagnetic product, [{PC(sp2)P}HPtI]. The Evans method and EPR spectroscopy revealed that a one-electron oxidation occurred at the carbene carbon, thus generating a persistent radical carbene.

Chemoresponsive polymers are of technol. significance for smart sensors or systems capable of mol. recognition. An important key requirement for these applications is the material’s structural integrity after stimulation. We explored whether covalently crosslinked metal ion-phosphine coordination polymers (MPN) can be shaped into any temporary shape and are capable of recovering from this upon chemoresponsive exposure to triphenylphosphine (Ph3P) ligands, whereas the MPN provide structural integrity. Depending on the metal-ion concentration used during synthesis of the MPN, the degree of swelling of the coordination polymer networks could be adjusted. Once the MPN was immersed into Ph3P solution, the reversible ligand-exchange reaction between the metal ions and the free Ph3P in solution causes a decrease of the coordination crosslink d. in MPN again. The Ph3P-treated MPN was able to maintain its original shape, indicating a certain stability of shape even after stimulation. In this way, chemoresponsive control of the elastic properties (increase in volume and decrease of mech. strength) of the MPN was demonstrated. This remarkable behavior motivated us to explore whether the MPN are capable of a chemoresponsive shape-memory effect. In initial experiments, shape fixity of around 60% and shape recovery of almost 90% were achieved when the MPN was exposed to Ph3P in case of rhodium. Potential applications for chemoresponsive shape-memory systems could be shapable semiconductors, e.g., for lighting or catalysts, which provide catalytic activity on demand.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Stereochemical Effects on Platinum Acetylide Two-Photon Chromophores, published in 2019-10-31, which mentions a compound: 12080-32-9, mainly applied to stereochem effect platinum acetylide two photon nonlinear absorption chromophore, Application of 12080-32-9.

Cis-Pt(II) acetylide complexes containing 2-photon-absorbing chromophores were synthesized and characterized to explore the effects of stereochem. on the nonlinear absorption properties. The mols. feature 4-(phenylethynyl)phenylethynylene (PE2), diphenylaminofluorene (DPAF), and benzothiazolylfluorene (BTF) ligands. The photophys. properties were studied under 1- and 2-photon conditions and compared to the known trans analogs via UV-visible absorption, luminescence, femtosecond and nanosecond transient absorption (TA), nanosecond z-scan, and femtosecond 2-photon absorption (2PA). The bent cis complexes exhibit blue shifts in the absorption, emission, femtosecond, and nanosecond TA spectra along with lower molar absorptivities and lower phosphorescence yields relative to the trans complexes suggesting less efficient Pt-induced spin-orbit coupling and intersystem crossing in the cis configuration. The cis chromophores are noncentrosym. and therefore show dipolar behavior with a pronounced 2PA in the 0-0 transition of the S0 → S1 band, while the trans complexes show quadrupolar behavior with a forbidden 0-0 transition. In the S0 → Sn region, both cis and trans complexes show intense 2-photon-absorption bands (up to 3700 GM by the peak cross section for cis-BTF) which contain a significant contribution from the excited state absorption (S1 → Sn). All 6 complexes exhibit comparable nonlinear absorption response with a significant contribution from triplet-triplet absorption that slightly favors trans complexes but is more strongly dependent upon the structure of the π-conjugated chromophore. Crystallog. data are given.

Recommanded Product: 12080-32-9. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about 2-Adamantyl Complexes of Platinum. Author is Taullaj, Fioralba; Armstrong, David; Datta, Shaishav; Lough, Alan J.; Fekl, Ulrich.

The first adamantyl platinum complexes were isolated and characterized, namely [(COD)Pt(2-Ad)Cl], [(dppe)Pt(2-Ad)Cl], [(COD)Pt(2-Ad)Me] and, [(dppe)Pt(2-Ad)Me] {COD = 1,5- cyclooctadiene, dppe = 1,2-bis(diphenylphosphino)ethane, Ad = adamantyl}. These complexes show considerable stability, including resistance to heating to 125° in solution for several days. It is therefore concluded that previously existing road blocks to synthesizing platinum adamantyls were due to complications in the transmetalation step, and not due to intrinsic instability of the final product. Counterintuitively, the key to successful transmetalation from ZnII onto PtII is imposing slow reaction progress via use of a solvent in which both the platinum chloride precursor and adamantyl anion precursor are poorly soluble
