二氰基二硫纶·邻菲咯啉-5,6-二酮混配锰(Ⅱ)、铁(Ⅱ)、钴(Ⅱ)配合物的感光氧化特性

摘要

The electronic absorption spectra of complexes M(mnt) (phen-5, 6-dione) (M = Mn2+ , Fe2+ , Co2+ ; mnt2- = 1,2-dicyano-1, 2-ethylenedithiolate; phen-5,6-dione = 1,10-phenanthroline-5,6-dione) in DMSO, acetone and CHCl3 were reported. The relationship between electronic spectrum absorption band and correlative transition in the molecular orbital energy level diagram of complex were investigated. The essence characteristics of interligand charge transfer transition(LL'CT) were dissected. The photooxydation characteristics of complexes of M(mnt)(phen-5,6-dione) in DMSO were ascertained.%测定了二氰基二硫纶·邻菲咯啉-5,6-二酮混配锰(Ⅱ)、铁(Ⅱ)、钴(Ⅱ)配合物MLL'(M=Mn2+、Fe2+、Co2+；L=mnt2-,1,2-二氰基乙烯-1,2-二硫醇离子；L'=phen-5,6-dione,1,10-邻菲咯啉-5,6-二酮)在二甲基亚砜(DMSO)、丙酮(Acet)和氯仿(CHCl3)中的电子吸收光谱,研究了电子光谱吸收带在相关分子轨道能级图中的对应跃迁关系,探讨了它们在DMSO中的感光氧化特性.
