以3-硝基邻苯二腈和4-硝基邻苯二腈为原料经过两步反应合成了α和β-四甲氧基苯氧基酞菁锌,通过IR光谱、UV-Vis光谱、MS谱、1H NMR谱和元素分析表征了其结构,其结果与标题化合物的结构一致.这两种酞菁在有机溶剂中有良好的溶解性.通过循环伏安法研究其能带结构和电化学过程,结果表明,甲氧基苯氧基在α-位时(与苯氧基在β-位时相比)酞菁单体的HOMO能级升高,LUMO能级降低,带隙变窄,有利于酞菁分子的电子传输.它们在二氯甲烷中的电化学过程都是单电子准可逆过程,而且氧化还原过程均发生在酞菁环上.最后提出了两种酞菁的电化学反应机理. The α and β-tetramethoxyphenoxy phthalocyanine were synthesized by the reaction of 3-nitrophthalonitrile and 4-nitrophthalonitrile in two steps. IR spectra, UV-Vis spectra, MS spectra, 1H NMR spectrum and elemental analysis showed that the structures of these two phthalocyanines were in good agreement with that of the title compound. The two phthalocyanines showed good solubility in organic solvents. The cyclic voltammetry The results show that the HOMO level of the methoxyphenoxy group at the α-position (compared with the phenoxy group at the β-position) increases, the LUMO energy level decreases and the band gap narrows , Which is conducive to the electron transport of phthalocyanine molecules.The electrochemical processes in methylene chloride are all single-electron quasi-reversible processes, and the redox process takes place on the phthalocyanine ring.Finally, two kinds of phthalocyanine electrochemistry Reaction mechanism.
