| Abstract: | A kind of new material consisting of Re centralion and benzimidazole ligands had been deve loped.These novel luminescent complexes were synthesized.In the solid state,these complexes 1,and 2 have an emission maximum at 543,577 nm,respectively.They display yellow,green luminescence and have high luminescence quantum efficiency.The luminescent properties of Re (I) pyridyl-imidazole complex was also investigated,the assignment of emission was notable metal to ligand charge transfer (MLCT) process upon dπ→π~*(L) transition. |
