以1,5-二羟基萘、4-硝基邻苯二甲腈、间苯二酚、乙酰乙酸乙酯以及醋酸锌为主要原料, 合成了9(10),16(17),23(24)-三[4-甲基-7-香豆素氧基]-2(3)-(1,5-二氧基萘)双核锌酞菁(bi-CPc). 利用1H NMR、FT-IR、UV-Vis、元素分析、热重分析等手段对前驱体和bi-CPc的结构和性能进行 表征. 结果表明, bi-CPc的紫外可见吸收光谱表现出强烈的π-π*跃迁且在N,N-二甲基甲酰胺(DMF)溶液中以单体形式存在, 并且具有良好的热稳定性. 用循环伏安法研究了bi-CPc的氧化还原行为, 计算其LUMO和HOMO能级与纳米TiO2能级匹配. 通过进一步结构修饰, 有望作为性能良好的光敏染料用于太阳能电池.

9(10),16(17),23(24)-Tris[4-methyl-coumarin-7-yloxy]-2(3)-(1,5-naphthalene) binuclear zinc phthalocyanine (bi-CPc) based 1,5-dihydroxynaphthalene, 4-nitro-phthalonitrile, resorcinol, ethyl acetoacetate and zinc acetate on raw material was synthesized. The structures and properties of precursors and bi-CPc were characterized by 1H NMR, FT-IR, UV-Vis, elemental analysis and thermogravimetric analysis. Results showed that strong π-π* transition was demonstrated by UV-Vis absorption spectrum of bi-CPc. At the same time, it existed in a form of monomer in solution of N,N-dimethylformamide (DMF) and possessed excellent thermal stability. Redox behavior of bi-CPc was researched by cyclic voltammetry (CV), and energy level of LUMO and HOMO of bi-CPc matched with energy level of nano-TiO2 after calculating. Through further structural modification, it is expected to use as photosensitive dye with excellent performance for solar cells.
