【摘要】 合成了Pd(Ⅱ)与2-(邻-氯苯基)苯并咪唑(OCBM)的配合物，采用元素分析、UV、IR、摩尔电导率等进行表征。圆二色性研究发现，配合物在187 nm和245 nm处呈正科顿效应，而在193 nm处呈负科顿效应。荧光性质研究表明，配合物的特征荧光发射峰出现在578 nm和592 nm处，荧光寿命τ578和τ592分别为0.25 ns和0.30 ns。Pd(Ⅱ)配合物可发射黄色和黄绿色荧光。更多还原

【Abstract】 A complex of Pd(Ⅱ) with 2-(O-chlorophenyl)benzimidazole(OCBM) was synthesized and characterized by elemental analysis, UV, IR, molar conductivity, etc.The circular dichroism study found that the complex exhibits a positive Cotton effect at 187 nm and 245 nm, while a negative Cotton effect is observed at 193 nm.Studies on fluorescence properties have shown that the characteristic fluorescence emission peaks of the complex appear at 578 nm and 592 nm, with fluorescence lifetimes τ578 and τ592 of 0.25 ns and 0.30 ns, respectively.Pd(Ⅱ) complexes can emit yellow and yellow green fluorescence.更多还原
