【摘要】 设计合成了水杨醛缩对硝基苯胺(HL)及其锌配合物(ZnL2),用元素分析、IR、热重分析等方法对产物结构进行了表征。并采用循环伏安法研究了配合物ZnL2在DMF和DMSO溶液中的电化学性质,可以观察到1个单电子氧化还原过程,对应于配合物分子内Zn2+/Zn+电对的电子转移过程。并对比研究了两个化合物在甲醇、无水乙醇、DMF溶液中的荧光性质,荧光光谱表明,配体与配合物在甲醇、乙醇、DMF溶液中能够发射较强的荧光,配合物ZnL2发光机理为金属离子微扰下配体的π*→n发光。更多还原

【Abstract】 Salicylidene-p-nitroaniline(HL) and its Zinc(Ⅱ) complex ZnL2 were synthesized,and that characterized by element analysis,IR,TG,DSC and so on.The electrochemical property of ZnL2 in DMSO and DMF were studied by cyclic voltammetry.The redox process of one single electron corresponded to electron transfer process of Zn2+/Zn+ in complex.The fluorescence property of ligand and zinc complex in methanol,anhydrous ethanol and DMF were studied,and ligand and zinc complex in them had stronger fluorescence.The above mentioned photoluminescence peaks could be ascribed to the band of π*→n transition in the ligand in disturbing of metal ion.更多还原
