Coordination polymers (CPs) with Bi(III) as a connectivity center were prepared from BiX3 (X = Cl-I) and 4,4′-bipyridine (bipy) to implement Bi-based luminescence. The products were obtained via different synthetic routes such as solution chem., melt syntheses or mechanochem. reactions. Five neutral and anionic 1-dimensional-CPs are presented that show a chem. parallel to trivalent lanthanides forming isostructural or closely related 1-dimensional-CPs, of which five addnl. compounds are described. Bi3+ proves to be a versatile cation for luminescence resulting from energy transfer processes between a metal and a ligand in the presented CPs. Quantum chem. calculations were carried out to study Bi3+-participation in the luminescence processes. The calculated results allow an assignment of the bright transitions composed of mainly metal-to-ligand-charge transfer (MLCT) character. Bi3+ can form strongly luminescent coordination compounds with N-donor ligands. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Safety of Pyridinehydrochloride).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Safety of Pyridinehydrochloride
