Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 15227-42-6, is researched, SMILESS is [Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2, Molecular C10H10Cl2N2PtJournal, Journal of Luminescence called Luminescence properties of some platinum(II) complexes. Counter-ion and molecular geometry effects, Author is Diomedi Camassei, F.; Ancarani-Rossiello, L.; Castelli, F., the main research direction is reflection platinum complex structure; luminescence platinum complex structure; phosphorescence platinum complex structure; counter ion platinum complex.Electric Literature of C10H10Cl2N2Pt.

Reflectance and luminescence spectra, and emission lifetimes of 14 charged and neutral Pt(II) crystalline complexes are reported. The lifetimes (in the range of some tens of μsec) indicate that the emissions are due to a spin-forbidden process. On the basis of spectral correlations, the phosphorescence is tentatively identified as due to the lowest d-d ligand field transition when the bonding of the ligand is essentially σ in character, and to a π* → d charge-transfer transition for those complexes in which the ligands themselves have π orbital systems. Both the radiative (kr) and nonradiative (kn) rate constants are sensitive to changes in mol. geometry (cis,trans isomers) and counter-ions. By assuming unitary efficiency for the intersystem crossing to the emitting state, the counter-ion appears to predominantly affect kn through vibrational coupling of the chromophore with the lattice. For the cis forms, both kr and kn are affected in a complex manner, with metal-metal interactions playing an important role. For the trans forms, however, the constancy of the quantum yield with respect to temperature suggests that kn is negligible in comparison to kr, and therefore the trans chromophores behave as isolated systems within the crystalline lattice.

SDS of cas: 15227-42-6. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles.

F..

Kinetic data were obtained for the hydrolysis of [PtenCl2], cis- and trans-[Pt(NH3)2Cl2], cis-[Ptpy2Cl2], and [Pten(NO2)Cl] and for the replacement of Cl by NH3 in trans-[Pt(NH3)2Cl2]. The medium was H2O and mixtures of H2O with MeOH, EtOH, or Me2CO, the concentration of the organic component being 30 and 40 weight % in the hydrolysis and replacement reactions, resp. The lowering of the reaction rate in the presence of the organic component is explained by a structure-dependent contribution of the component to the solvation energy of an intermediate complex. The hydrolysis reaction is assumed to proceed in 2 steps: (1) formation of an intermediate complex by a slow coordination of the H2O mol. to the Pt2+ central ion without release of Cl- and (2) by a quick release of Cl-. The bond polarization occurs during the 1st step and the rate constant, k, should equal the ratio of the activity coefficients of the initial and activated complexes.

The synthesis and characterization of a polymeric structure containing fluorene units statistically linked to 3-cyclohexyl-thiophene and bipyridine PFOTBipy-poly[(4-hexylthiophene-2,5-diyl)(9,9-dihexyl-fluoren-2,7-diyl)-co-(bipyridine-5.5′-diyl)(9,9-dihexyl-fluoren-2,7-diyl)], is reported. The complexation with platinum was possible through the bipyridil units present in 10%, 50% and 100% content. The structure has a fluorenyl moiety between each bipyridine and thiophene groups resulting in a stable and efficient light-emitting polymeric material combining the well known emissive properties of fluorene, the charge mobility generated by thiophene and the electron-transfer properties of a metal complex as well. All the polymers were photo and electroluminescent materials, and showed phosphorescence at low temperatures Photoluminescence properties were studied by steady state and time resolved spectroscopy and showed changes of both emission peak and relative intensity of the emission bands depending on the relative amount of the platinum complex. The electroluminescence followed the trends found for photoluminescence. The blue emission of the copolymer without platinum is due to the fluorenyl segments and for higher complex contents the emission is characteristic of the aggregates involving the bipyridinyl moieties. Therefore, emission color can be tuned by the complex content. The turn-on voltage was strongly reduced from 22 to 8 V for the 100% complexed copolymer, as compared to the device made with the non complexed one, but the luminance decreased, due to quenching or trapping effects.

cis-[PtL2Cl2] (L = Et2NOH) was prepared by the reaction of K2PtCl4 with L. cis-[PtL2Cl2] does not react with amines (NH3, pyridine, Et2NOH) and L does not react with cis-[PtA2Cl2] (A = NH3, py). cis-[PtL2Cl2] is monoclinic, space group C2, a 7.569(2), b 12.384(7), c 15.428(2) Å, β 100.00(2)°, Z = 4, R = 0.0287. One L coordinates to Pt through the N atom whereas the other is in the zwitterionic form and coordinates through the O atom. The low reactivity of cis-[PtL2Cl2] in substitution reactions is explained on the basis of H bonding and agostic interactions due to which the axial positions in the square planar complexes are blocked against nucleophilic attack.

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 Quantitative measurement of the reduction of platinum(iv) complexes using X-ray absorption near-edge spectroscopy (XANES), published in 2012, which mentions a compound: 15227-42-6, Name is cis-Dichlorobis(pyridine)platinum(II), Molecular C10H10Cl2N2Pt, Recommanded Product: cis-Dichlorobis(pyridine)platinum(II).

The platinum(ii) drugs cisplatin, carboplatin and oxaliplatin are usefully employed against a range of malignancies, but toxicities and resistance have spurred the search for improved analogs. This has included investigation of the platinum(iv) oxidation state, which provides greater kinetic inertness. It is generally accepted that Pt(iv) complexes must be reduced to Pt(ii) for activation. As such, the ability to monitor reduction of Pt(iv) complexes is critical to guiding the design of candidates, and providing mechanistic understanding. Here we report in full that the white line height of X-ray absorption near-edge spectra (XANES) of Pt complexes, normalized to the post-edge min., can be used to quant. determine the proportion of each oxidation state in a mixture A series of Pt(iv) complexes based on the Pt(ii) complexes cisplatin and transplatin were prepared with chlorido, acetato or hydroxido axial ligands, and studies into their reduction potential and cytotoxicity against A2780 human ovarian cancer cells were performed, demonstrating the relationship between reduction potential and cytotoxicity. Anal. of white line height demonstrated a clear and consistent difference between Pt(ii) (1.52 ± 0.05) and Pt(iv) (2.43 ± 0.19) complexes. Reduction of Pt(iv) complexes over time in cell growth media and A2780 cells was observed by XANES, and shown to correspond with their reduction potentials and cytotoxicities. We propose that this method is useful for monitoring reduction of metal-based drug candidates in complex biol. systems.
