White light emission from a green cyclometalated platinum() terpyridylphenylacetylide upon titration with Zn() and Eu( )
The cyclometalated Pt( ii ) acetylide derivative with a 1,3-bis( N -octyl-benzimidazol-2-yl)benzene (N^C^N) ligand and a free terpyridine (TPY) receptor has been successfully synthesized and characterized. X-ray crystallography shows its inefficient conjugation degree between the [(N^C^N)Pt] and TPY...
