摘　　要：以酞菁铜、氯磺酸和氯化亚砜为原料合成酞菁铜磺酰氯,并将其与本征态聚苯胺进行反应,合成了侧链悬挂酞菁铜功能基的聚苯胺(PAnCuPc)。用元素分析、红外光谱和紫外-可见吸收光谱对产物和反应中间体进行了结构表征。PAnCuPc可溶于强极性非质子溶剂。如NMP,DMF,DMSO和DMAc,甚至在常用的低沸点溶剂如THF和三氯甲烷中也有一定的溶解性。红外光谱研究表明,与本征态聚苯胺相比,侧链含酞菁铜功能基的聚苯胺的吸收峰向低频方向移动。紫外-可见吸收光谱表明,侧链悬挂酞菁铜功能基的聚苯胺在可见光区和近红外区都具有较强的吸收。透射电镜和X射线衍射研究表明,该产物具有较强的结晶性能。Using Cu-phthalocyanine, chlorosulfonic acid and sulfone chloride as raw materials, Cu-phthalocyanine sulfonic acid chloride was synthesized. The polyaniline containing Cu-phthalocyanine functional group in side chain (PAnCuPc) was synthesized by using Cu-phthalocyanine sulfonic acid chloride and intrinsic polyaniline. The designed chemical structure of PAnCuPc and its intermediate product can be proved by means of the elementary analysis, IR and UV-Vis. PAnCuPc is soluble in aprotic solvents such as NMP, DMF, DMAc and DMSO. It is even soluble in common solvents with a low boiling point such as THF and chloroform. In comparison with the intrinsic polyaniline, the absorption peaks of PAnCuPc shift to a low frequency direction in IR spectrum. The absorption of PAnCuPc is very intense in the range of visible light and near-infrared through UV-Vis spectrum. It can be seen from transition electron microscopy and X-ray diffraction that the crystallinity of PAnCuPc is obviously improved.
