以含有咪唑阳离子的邻苯二腈为前驱体,通过环合反应分别合成了四咪唑阳离子取代的锌酞菁和铜酞菁,它们的结构均通过了红外光谱、核磁氢谱、元素分析和紫外-可见吸收光谱的表征.这2种酞菁化合物在水、DMF、DMSO及甲醇中均呈现出良好的溶解性.利用紫外-可见吸收光谱法考察了它们在不同种溶剂中、不同浓度下的聚集行为,并利用循环伏安法和方波伏安法测试了它们的电化学性质.
In this work,two water-soluble cationic Zn(Ⅱ)(3)and Cu(Ⅱ)(4)phthalocyanines peripherally tetra-substituted with imidazolium cations were synthesized through a direct cyclotetramerization of cationic phthalonitrile derivatives.These compounds were characterized by infrared spectroscopy(IR),1 H nuclear magnetic resonance(1 H NMR),mass spectrum(MS),elemental analysis and ultraviolet-visible(UV-Vis)spectral data.They all showed excellent solubility in water and some polar organic solvents such as methanol,dimethylsulfoxide(DMSO)and dimethylformamide(DMF).The aggregation behaviors of these complexes were investigated in different solvents and concentrations and their electrochemical properties were studied by cyclic voltammetry and square wave voltammetry.
