制备了Zn(Ⅱ) 与2-(O-氯苯基)苯并咪唑的配合物(ZCBB),在园二色性研究中发现,ZCBB在211、225和292nm处呈正科顿效应。固体三维荧光研究表明,ZCBB分子中苯并咪唑基团的特征荧光峰(λex/λem)出现在336/388nm和336/748nm处,苯并咪唑基团的荧光寿命τ388和τ748分别为0.73ns和0.60ns。在ZCBB的乙醇溶液中,苯并咪唑基团的特征荧光峰位于330/368nm和330/697nm处,它的荧光寿命τ368和τ697分别为0.57ns和0.63ns。ZCBB配合物可发射多种波长的荧光,是良好的荧光材料。
Zn(Ⅱ) complex with 2-(O-chlorophenyl) benzimidazole(ZCBB) was prepared. It was found that Ⅱ ZCBB showed positive Cotton effect at 2l1 , 225 and 292 nm in CD study. The characteristic fluorescence peaks(kex/kem) of benzimidazolyl group were located at 336/388 and 336/748 nm in three-dimension fluo- rescence spectrum of solid ZCBB, its lifetimes r388 and τ748 were 0.73 and 0.60 ns respectively. In ZCBB ethanol solution, the characteristic fluorescence peaks of benzimidazolyl group appeared in 330/368 and 330/697 nm, its lifetimes z368 and τ696 were 0.57 and 0.63 ns respectively. ZCBB complex emitted multi- wavelength fluorescence, it was a very good fluoreseent material.
