摘要
以4-硝基邻苯二甲腈、亚氨基二乙酸、8-羟基喹啉等化合物为原料,合成了一种不对称羧基锌酞菁,2-(8-氧基喹啉)-9,16,23-(N,N-二乙酸胺基)酞箐锌。通过红外光谱、紫外-可见光谱、核磁共振氢谱对其进行结构表征,Q带吸收波长为680 nm,B带为358nm。利用循环伏安法和差分脉冲伏安法,结合紫外-可见吸收光谱,得到其基态氧化电位(0.93 V)和激发态氧化电位(-0.89V)能级位置与纳米TiO2导带能级相匹配,可用于制备染料敏化太阳能电池。
The synthesis of 2-(N,N-diacetic acid amino)-9,16,23-(8- ethoxyquin)- phthalocyanine zinc from 4-nitrophthalonitrile was investigated.The new zinc phthalocyanine was characterized by IR,1H NMR,UV-Vis,cyclic voltanimetry as well as differentia]pulse voltammetry.From the reduction and oxidation behavior,it is proved that OPC has negative LUMO level and positive HOMO level,satisfying the energy gap rule,OPC can be employed as sensitizers for DSSC applications.
