Studies on Synthesis and Special Properties of Pd(Ⅱ)Complex with Chlorophenyl Benzimidazole
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.
