Computed Properties of C8H12Cl2Pt. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. 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.

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 Photophysical Properties of Phosphorescent Mono- and Bimetallic Platinum(II) Complexes with C C* Cyclometalating NHC Ligands, the main research direction is imidazopyridinyl bimetallic platinum pyrazolate complex preparation electronic structure phosphorescence; crystal structure imidazopyridine bimetallic platinum pyrazolate complex; mol structure imidazopyridine bimetallic platinum pyrazolate complex; imidazopyridine cyclometalation platinum complex.Recommanded Product: 12080-32-9.

Due to their square-planar geometry, Pt(II) complexes demonstrate an extraordinary and unique photophys. behavior. The photophys. properties of monometallic Pt(II) complexes depend on the concentration, while in bimetallic Pt(II) complexes they depend on the distance between the metal centers. The authors reveal a correlation between the electronic and photophys. properties of monomeric monometallic Pt(II) complexes and their aggregates with the corresponding bimetallic complexes.

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.
