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, Journal of Catalysis called Highly efficient hydrosilylation catalysts based on chloroplatinate “”ionic liquids””, Author is Jankowska-Wajda, Magdalena; Bartlewicz, Olga; Walczak, Anna; Stefankiewicz, Artur R.; Maciejewski, Hieronim, which mentions a compound: 12080-32-9, SMILESS is C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-], Molecular C8H12Cl2Pt, Application of 12080-32-9.

The reaction between ionic liquid [Cat]+Cl- (where Cat stands for 1-butyl-3-methylimidazolium, 1-butyl-2,3-dimethylimidazolium or 1-butyl-4-methylpyridinium) and the metal precursor ([PtCl2(cod)], PtCl4, K2[PtCl4] or K2[PtCl6]) yielded two groups of derivatives: [Cat]+[PtCl4]- and [Cat]+[PtCl6]-, which formally are counted among halometallate ionic liquids, however, due to their high m.ps. they should be classified into anionic platinum complexes rather than into ionic liquids All the derivatives were isolated and characterized spectroscopically (NMR, ESI-MS) and crystallog. structures were determined for three derivatives: ([BMPy]2[PtCl4], [BMIM]2[PtCl6] and [BMMIM]2[PtCl6]). Moreover, their m.ps. were measured and thermal stability was assessed. The above derivatives were employed as catalysts for hydrosilylation of olefins with diverse properties. All the studied catalysts showed high activity and their insolubility in the reaction medium made easy their isolation and multiple use in subsequent catalytic runs. The most effective catalysts did not lose their activity even after ten runs, thereby they make a very good alternative to commonly used homogeneous catalysts. Their simple synthesis and stability make them interesting both for economic and ecol. reasons.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 12080-32-9, is researched, Molecular C8H12Cl2Pt, about Spectroscopic, structural and DFT studies of luminescent Pt(II) and Ag(I) complexes with an asymmetric 2,2′-bipyridine chelating ligand, the main research direction is carbomethoxybipyridine preparation platinum silver complexation; crystal mol structure methylcarbomethoxybipyridine platinum silver complex; DFT luminescent platinum silver methylcarbomethoxybipyridine asym bipyridine chelating ligand.Electric Literature of C8H12Cl2Pt.

A new unsym. substituted 2,2′-bipyridine ligand, 5-methyl-5′-carbomethoxy-2,2′-bipyridine (L) was isolated from the dry distillation of the copper(II) complex, mono-aqua-bis(trans-5-methyl-pyridine-2-carboxylato-N,O)copper(II). The ligand was fully characterized. The spectroscopic and single-crystal x-ray diffraction (SCXRD) studies of the coordination compounds of the ligand with platinum(II) and silver(I); cis-Pt(L)Cl2 (1) and [Ag(L)2]PF6 (2), resp. are reported. In 1, the Pt center coordinates to tertiary N atoms of the ligand and two chloride ions to form a neutral square-planar coordination sphere, while in 2, the Ag(I) center is coordinated by two ligands through N atoms to generate a cationic flattened tetrahedron geometry in which two mean planes intersect each other at 50.93°. The pyridine rings are nearly coplanar as revealed by the torsion angle of N2-C7-C6-N1 1.32(5)°. In both complexes, L acts as a chelating ligand through pyridyl N atoms. In 1, the mol. units are stacked in a head-to-tail fashion with a Pt···Pt separation of 3.5 Å. Supramol. self-assembly of the mol. units by extensive intermol. contacts through C-H···Cl and C-H···O between the adjacent units results in an infinite two-dimensional flattened-out herringbone structure in the crystalline state. In 2, the mol. units are interconnected with each other by C-H···O contacts between the adjacent units running parallel to each other. Both complexes are fluorescent in solution and have emission maxima in the UV-Vis regions, which is a very important property for optoelectronic applications. DFT (d. functional theory) and TD-DFT (time-dependent-DFT) calculations were performed at B3LYP/6-311+G(d,p)/LANL2DZ level to explore structural, electronic, and spectroscopic properties to compare with the exptl. results. The MOs were carried out with DFT at the same level.

The use of organometallic triplet emitters in organic light emitting diodes (OLEDs) is motivated by the premise of efficient intersystem crossing leading to unit internal quantum efficiencies. However, since most devices are based on solid-state components, an inherent limitation to square-planar Pt(II) phosphors is their tendency toward aggregation-based quenching. Here, a new class of emissive, four-coordinate Pt(II) species based on the bisimidazolyl carbazolide (BIMCA) ligand is introduced, which displays highly efficient, long-lived solid-state phosphorescence at room temperature A set of four BIMCAPt Ph acetylides were synthesized that emit in the green (λmax=507-540 nm) with >60% quantum yield and millisecond lifetimes. The structures of the resulting species reveal a nonplanar structure imposed by steric clashes between BIMCA and the iodo or alkynyl co-ligand. Ground-state and photophys. characterization are presented. D. functional theory calculations indicate that the BIMCA ligand dominates the frontier orbitals along with the 1st Franck-Condon singlet and triplet excited states.

This Account describes a body of research on the design, synthesis, and application of a new class of electronic materials made from conjugated macrocycles. Our macrocyclic design takes into consideration the useful attributes of fullerenes and what properties make fullerenes efficient n-type materials. We identified four electronic and structural elements: (1) a three-dimensional shape; (2) a conjugated and delocalized π-space; (3) the presence of an interior and exterior to the π-surface; and (4) low-energy unoccupied MOs allowing them to accept electrons. The macrocyclic design incorporates some of these properties, including a three-dimensional shape, an interior/exterior to the π-surface, and low-lying LUMOs maintaining the n-type semiconducting behavior, yet we also install synthetic flexibility in our approach in order to tune the properties further. Each of the macrocycles comprises perylenediimide cores wound together with linkers. The perylenediimide building block endows each macrocycle with the ability to accept electrons, while the synthetic flexibility to install different linkers allows us to create macrocycles with different electronic properties and sizes. We have created three macrocycles that all absorb well into the visible range of the solar spectrum and possess different shapes and sizes. We then use these materials in an array of applications that take advantage of their ability to function as n-type semiconductors, absorb in the visible range of the solar spectrum, and possess intramol. cavities. This Account will discuss our progress in incorporating these new macrocycles in organic solar cells, organic photodetectors, organic field effect transistors, and sensors. The macrocycles outperform acyclic controls in organic solar cells. We find the more rigid macrocyclic structure results in less intrinsic charges and lower dark current in organic photodetectors. Our macrocyclic-based photodetector has the highest detectivity of non-fullerene acceptors. The macrocycles also function as sensors and are able to recognize nuanced differences in analytes. Perylenediimide-based fused oligomers are efficient materials in both organic solar cells and field effect transistors. We will use the oligomers to construct macrocycles for use in solar energy conversion. In addition, we will incorporate different electron-rich linkers in our cycles in an attempt to engineer the HOMO/LUMO gap further. Looking further into the future, we envision opportunities in applying these conjugated macrocycles as electronic host/guest materials, as concatenated electronic materials by threading the macrocycles with electroactive oligomers, and as a locus for catalysis that is driven by light and elec. fields.

Category: alcohols-buliding-blocks. 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 A sterically congested 1,2-diphosphino-1′-boryl-ferrocene: synthesis, characterization and coordination to platinum.

A new class of tritopic ferrocene-based ambiphilic compounds has been prepared by assembling diphosphino- and boryl-substituted cyclopentadienides at iron. The presence of five sterically demanding substituents on the ferrocene platform induces conformational constraints, as is apparent from XRD and NMR data, but does not prevent the chelating coordination to platinum. The Lewis acid moiety is pendant in both the free ligand and the platinum complex.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Sutton, Ryan B.; Henderson, William researched the compound: Dichloro(1,5-cyclooctadiene)platinum(II)( cas:12080-32-9 ).HPLC of Formula: 12080-32-9.They published the article 《The water-solubilisation of the metalloligand [Pt2(μ2-S)2(PPh3)4] using 1,3,5-triaza-7-phospha-adamantane (PTA)》 about this compound( cas:12080-32-9 ) in Inorganica Chimica Acta. Keywords: platinum triazaphosphaadamantane complex preparation stability ESI mass spectra. We’ll tell you more about this compound (cas:12080-32-9).

The synthesis of the platinum(II) μ2-sulfide complex [Pt2(μ2-S)2(PTA)4] (PTA = phosphatriazaadamantane), as a water-soluble analog of the known triphenylphosphine complex [Pt2(μ2-S)2(PPh3)4], was explored through a range of synthetic routes. A direct synthesis, from cis-[PtCl2(PTA)2] and Na2S·9H2O in benzene is the most effective, while attempted ligand substitution of the PPh3 ligands of [Pt2(μ2-S)2(PPh3)4] with PTA resulted in rearrangement of the {Pt2S2} core, and formation of a series of PTA-substituted trinuclear species of the general composition [Pt3(μ3-S)2(PPh3)x(PTA)6-x]2+. The fully-substituted complex [Pt3(μ3-S)2(PTA)6]2+ was also obtained when cis-[PtCl2(PTA)2] was reacted with a sulfide ion-exchange resin. Reaction of [PtCl2(cod)] (cod = 1,5-cyclooctadiene) with Na2S·9H2O in benzene gave a red solid identified as crude [Pt2(μ2-S)2(cod)2]. Reaction of this labile {Pt2S2} precursor with PTA gave [Pt2(μ2-S)2(PTA)4] along with PTA -oxide and -sulfide. ESI mass spectrometry was widely employed as a convenient tool for exploring this chem., in conjunction with 31P{1H} NMR spectroscopy. These PTA-Pt-sulfide species, especially those containing {Pt2S2} cores, have a tendency to decompose in solution Addnl. confirmation of the formation of [Pt2(μ2-S)2(PTA)4] was provided by its reaction with [Rh2(μ2-Cl)2(cod)2], giving the adduct [Pt2(μ3-S)2(PTA)4Rh(cod)]+, identified using ESI MS.
