Charge-transfer (CT)-photolysis of Cu(II) dithiocarbamate mixed-ligand complexes Cu(II)(Et2dtc)X (X = Cl-, Br-) and Cu(II)(Et2dtc)(+)...Y- (Y = ClO4-, NO3-) has been studied in toluene/ROH and compared with our previous data obtained in chloromethane/ROH solutions, where chloromethane = CCl4, CHCl3 or CH2Cl2 and ROH = MeOH, EtOH, i-PrOH or i-BuOH. An EPR evidence is obtained about the formation of
铜(II)二硫代氨基甲酸酯混合配体配合物Cu(II)(Et2dtc)X(X = Cl-,Br-)和Cu(II)(Et2dtc)(+)...的电荷转移(CT)-光解-(Y = ClO4-,NO3-)已在甲苯/ ROH中进行了研究,并与我们先前在氯甲烷/ ROH溶液中获得的数据进行了比较,其中氯甲烷= CCl4,CHCl3或CH2Cl2,ROH = MeOH,EtOH,i-PrOH或i -BuOH。EPR证据表明,在甲苯/ ROH中同时光解Cu(II)(Et2dtc)+和Cu(II)(Et2dtc)2物种时,会形成新的二硫代氨基甲酸铜(II)混合配体络合物。通过分光光度法和EPR数据以及量子产率结果的组合分析,讨论了溶剂的作用。
