【摘要】 以过渡金属铼为中心金属离子,合成了2-(2-吡啶)苯并咪唑(HL1)和2,6-二(苯并咪唑)吡啶(HL2)配合物.该配合物荧光量子产率高、化学性质稳定,在固体状态下,最大发射峰分别是543nm、577nm,处在绿光和黄光区.其发光基理是基态金属离子电荷向激发态配体跃迁(MLCT),属于金属离子与配体间的dπ→π*(L)的跃迁发光.更多还原

【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.更多还原
