摘要
合成了3种不同取代基四-4-(2,4-二特戊基苯氧基)酞菁铜(A)、四-4-(四氢糠氧基)酞菁铜(B)和四-4-(正壬氧基)酞菁铜(C).热重分析表明3种衍生物的稳定性的顺序:A>B>C.偏振紫外光谱数据得到的结果与∏-A曲线推得结果一致.3种配合物的溶液和LB膜的循环-伏安曲线均显示了准可逆的电化学性质,LB膜的循环-伏安曲线对称性比相应溶液中的大,A的氧化-还原峰的劈裂最小,C的劈裂最大,B居中.
Cu（Ⅱ）-tetre-4-（2,4-di-t-pentyl phenoxy） phthalocyanine（A）,4-（tetrephydrofurfuroxy） phthalocyanine（B）,4-（n-nonaoxy） phthalocyanine（C） were synthesized.The thermostability order was A〉B〉C.The orientation of molecular macrocycles in the LB films were examined by polarized UV-vis absorbance.It was confirmed that the orientation in LB films inherently depends upon those molecular states spreading monolayers on the water surface The compounds in the LB films and solutions have a good reversible redox potentials.The LB films indicated that the smaller peak splitting and more symmetrical shape than those of corresponding solutions.The compound A showed the smallest peak splitting and compound C is the biggest andthe compound B is middle.By the result,appropriate substitutents into phthalocyanine ringis in the films could be controlled.
