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543 nm、577 nm,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.
以過渡金屬錸為中心金屬離子,閤成瞭2-(2-吡啶)苯併咪唑(HL1)和2,6-二(苯併咪唑)吡啶(HL2)配閤物.該配閤物熒光量子產率高、化學性質穩定,在固體狀態下,最大髮射峰分彆是543 nm、577 nm,處在綠光和黃光區.其髮光基理是基態金屬離子電荷嚮激髮態配體躍遷(MLCT),屬于金屬離子與配體間的dπ→π~*(L)的躍遷髮光.

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.
