摘要 苯并咪唑与碘苯在Cu I催化下经取代反应制得1,2-二苯基苯并咪唑(L);L与K2Pt Cl4在乙二醇单乙醚和水中经配位反应合成了两个新型的1,2-二苯基苯并咪唑铂(Ⅱ)配合物——L2Pt Cl(1)和L2Pt Cl2(2),其结构经1H NMR和X-射线单晶衍射表征。1的UV-Vis光谱显示明显的金属到配体的电荷转移跃迁,λmax位于238nm,279 nm,300 nm,315 nm和360 nm;2的λmax位于237 nm和285 nm。 1,2-Diphenyl-benzoimidazole (L) was prepared by substitution reaction of benzimidazole with iodo-benzene catalyzed by CuI. Two novel Pt( Ⅱ ) complexes, L2PtCI( 1 ) and L2PtC12 (2), were synthesized by coordination reaction of L with K2PtC14 in 2-ethoxyethanol/H20 solution. The structures were characterized by 1H NMR and X-ray single crystal diffraction. UV-Vis spectrum of 1 exhibited a classical metal-to-ligand charge transfer transition, λmax were 238 nm, 279 nm, 300 nm, 315 nm and 360 nm. λmax of 2 were 237 nm and 285 nm.
