摘　　要：详细报道了新近合成的二氰基二硫纶·邻菲罗啉二酮合镍配合物Ni(mnt) (phen - 5,6-dione) (mnt2 - ∶1,2 -dicyano - 1,2 -ethylenedithiolateormaleonitriledithiolate ;phen - 5,6-dione∶1,10 -phenanthroline - 5,6-dione)的电子吸收光谱 ,着重研究了可见光区中的溶剂化显色吸收带在相关分子轨道能级图中的对应跃迁关系 ,探讨了LL′CT的本质和感光氧化现象。The electronic absorption spectra of complex Ni(mnt) (phen-5,6-dione)(mnt 2- ,1,2-dicyano-1,2-ethy lenedithiolate or maleonitrile dithiolate,phen-5,6-dione,1,10-phenanthroline-5,6-dione) were reported in detail.The relation between solvatochromic absorption band in the visible range and correlative transition in the molecular orbital energy level diagram of complex Ni(mnt)(phen-5,6-dione) were emphatically investigated.The essence of interligand charge transfer transition (LL′CT) and photooxydation was ascertained.
