The microcrystalline structure of complex CuLL′(L=mnt2-,1,2-dicyano-1,2-ethylenedithiolate or maleonitriledithiolate.L′=5-NO2-phen,5-nitri-1,10-phenanthro line) was characterized by TEM and EDP.The title complex was microcrystalline particle approximate oval sphere about 30nm.The electronic absorption spectra and emission spectra of complex CuLL′in DMSO,DMF and CH3COCH3 were determined.The complex CuLL′exhibit strong absorption spectra bands and emission spectra bands at 260~530nm in solution.The dark conductivity and photoconductivity of CdS doped with CuLL′ were studied.The correlation between photosensitization of complex CuLL′to CdS and its electronic spectra was ascertained.The obvious matched properties was found to exist between the interligand charge transfer energy of complex CuLL′and forbidden band width(or photoconductive red limit) of CdS.
