| Abstract: | Reaction of 1,3-bis(1-pyrrolidinothiocarbonyl)benzene with PtCl2(PhCN)2 afforded a platinum complex with η3-S,C,S type coordination. The molecular structure of the SCS-pincer platinum(II) complex was determined by X-ray analysis. Substitution of chloro ligand with anionic ligands such as iodo and acetylide was carried out. The complexes exhibit strong emission in a glassy frozen state as well as in the solid state. Light-emitting diodes based on the complexes displayed red electroluminescence. |
