We present the synthesis and characterization of six novel bidentate C-C* cyclometalated platinum(II) complexes derived from saturated N-heterocyclic carbene precursors, namely 1-aryl-3-methyl-1H-4,5-dihydroimidazolium salts. The title compounds were then synthesized by a multi-step reaction, which includes an in situ generation of the silver carbene complex, followed by transmetalation to platinum and subsequent introduction of the β-diketonate ligand. Structural characterization by NMR experiments and solid-state structures prove the cyclometalation and the saturated backbone of the NHC motif. Photophys. and electrochem. properties of the platinum(II) complexes were examined and studied in detail by DFT calculations The title compounds are strongly emissive at room temperature in the sky-blue region of the visible spectrum and show quantum yields of up to 71% in a PMMA matrix.

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 Mustards-Derived Terpyridine-Platinum Complexes as Anticancer Agents: DNA Alkylation vs. Coordination, the main research direction is mustard terpyridine platinum complex preparation cancer DNA alkylation coordination.SDS of cas: 12080-32-9.

The development of bifunctional platinum complexes with the ability to interact with DNA via different binding modes is of interest in anticancer metallodrug research. Therefore, we report platinum(II) terpyridine complexes to target DNA by coordination and/or through a tethered alkylating moiety. The platinum complexes were evaluated for their in vitro antiproliferative properties against the human cancer cell lines HCT116 (colorectal), SW480 (colon), NCI-H460 (non-small cell lung), and SiHa (cervix) and generally exhibited potent antiproliferative activity although lower than their resp. terpyridine ligands. 1H NMR spectroscopy and/or ESI-MS studies on the aqueous stability and reactivity with various small biomols., acting as protein and DNA model compounds, were used to establish potential modes of action for these complexes. These investigations indicated rapid binding of complex PtL3 to the biomols. through coordination to the Pt center, while PtL4 in addition alkylated 9-ethylguanine. PtL3 was investigated for its reactivity to the model protein hen egg white lysozyme (HEWL) by protein crystallog. which allowed identification of the Nδ1 atom of His15 as the binding site.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Dichloro(1,5-cyclooctadiene)platinum(II)( cas:12080-32-9 ) is researched.COA of Formula: C8H12Cl2Pt.Norton, Amie E.; Sharma, Malvika; Cashen, Christina; Dourges, Marie-Anne; Toupance, Thierry; Krause, Jeanette A.; Motkuri, Radha Kishan; Connick, William B.; Chatterjee, Sayandev published the article 《pH-mediated colorimetric and luminescent sensing of aqueous nitrate anions by a platinum(II) luminophore@mesoporous silica composite》 about this compound( cas:12080-32-9 ) in ACS Applied Materials & Interfaces. Keywords: colorimetric luminescent sensor aqueous nitrate detection; platinum lumophore mesoporous silica composite; aqueous contaminant detection; environmental sensors; selectivity; sensitivity; water security. Let’s learn more about this compound (cas:12080-32-9).

Increased levels of nitrate (NO3-) in the environment can be detrimental to human health. Herein, we report a robust, cost-effective, and scalable, hybrid material-based colorimetric/luminescent sensor technol. for rapid, selective, sensitive, and interference-free in situ NO3- detection. These hybrid materials are based on a square-planar platinum(II) salt [Pt(tpy)Cl]PF6 (tpy = 2,2′;6′,2′′-terpyridine) supported on mesoporous silica. The platinum salt undergoes a vivid change in color and luminescence upon exposure to aqueous NO3- anions at pH ≤ 0 caused by substitution of the PF6- anions by aqueous NO3-. This change in photophysics of the platinum salt is induced by a rearrangement of its crystal lattice that leads to an extended Pt···Pt···Pt interaction, along with a concomitant change in its electronic structure. Furthermore, incorporating the material into mesoporous silica enhances the surface area and increases the detection sensitivity. A NO3- detection limit of 0.05 mM (3.1 ppm) is achieved, which is sufficiently lower than the ambient water quality limit of 0.16 mM (10 ppm) set by the United States Environmental Protection Agency. The colorimetric/luminescence of the hybrid material is highly selective to aqueous NO3- anions in the presence of other interfering anions, suggesting that this material is a promising candidate for the rapid NO3- detection and quantification in practical samples without separation, concentration, or other pretreatment steps.

Author is Sicard, Lambert; Lucas, Fabien; Jeannin, Olivier; Bouit, Pierre-Antoine; Rault-Berthelot, Joelle; Quinton, Cassandre; Poriel, Cyril.

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.

The aromatic metallole dianions are important metallaarom. compounds because of their various reactivities and extensive synthetic applications. Herein we report the reactions of dilithionickelole with MgCl2, EtAlCl2, Cp*ScCl2, Cp*LuCl2 and Pt(COD)Cl2 (COD = 1,5-cyclooctadiene) affording a series of Ni/M heterobimetallic complexes of the general formula [(η4-C4R4M)Ni(COD)], in which the metalloles act as diene ligands, as suggested by single-crystal X-ray, NMR and theor. analyses. In these reactions, two electrons of the nickelole dianion transferred to Ni, representing different reactivity compared with main-group metallole dianions.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Polymerization of vinyl acetate initiated by hydrosilane in the presence of platinum complex, published in 2021, which mentions a compound: 12080-32-9, Name is Dichloro(1,5-cyclooctadiene)platinum(II), Molecular C8H12Cl2Pt, Quality Control of Dichloro(1,5-cyclooctadiene)platinum(II).

In this work, a series of hydrosilanes including phenylsilane, diphenylsilane, triethylsilane (TES), and tris(trimethylsilyl)silane combined with catalytical amount of platinum complex such as dichloro(1,5-cyclooctadiene)platinum (COD) and dichloro(dicyclopentadienyl)platinum have been used to initiate the polymerization of vinyl acetate (VAc) at 70-95°C. An ultrahigh mol. weight PVAc with number-average mol. weight (Mn) up to 1.17 X 106 Da and polydispersity index (PDI) of 2.59 has been synthesized using TES as an initiator in the presence of 9.7 ppm of COD. A kinetic study indicates that the polymerization at VAc/TES/COD molar ratio = 3.0 X 105 : 60 : 1 smoothly reached 81.0% conversion in 28.0 h at 85°C, producing PVAc with Mn increasing linearly from 1.41 X 105 to 6.01 X 105 Da with the increase of monomer conversion. A mechanistic investigation revealed that COD was firstly reduced by reductive TES, producing Pt nanoparticles and corresponding silane radicals to initiate the polymerization of VAc.

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.
