摘要：

报导了聚2，5-二甲氧基苯胺（P25DMAn）的化学与电化学合成，并用元素分析、FTIR、UV－VIS吸收光谱、电导率测定以及电化学等手段对该聚合物进行了表征．P25DMAn类似聚苯胺（PAn）的结构，是由其单体通过氮原子N在对位上键合而成. P25DMAn是一种能溶于多种有机溶剂如THF、CH2Cl2、CHCl3、DMSO、DMF等．并具有极好的环境稳定性，优良的电活性和相当高的电导率的高聚物．因此，P25DMAn是一种很有应用前景的新的导电高聚物．

Abstract:

Poly (2,5-dimethoxyaniline) (P25DMAn) powder and film have been synthesized respectively by chemical and electrochemical methods. These polymers were characterized by elemental analysis, FTIR, UV-VIS spectroscopy, electrical conductivity measurement and cyclic voltammetry. The structure of P25DMAn is closed to that of polyaniline, with monomer units linked through the nitrogen atom and para-positions. P25DMAn can be dissolved in a variety of organic solvents (THF. CH2C12, CHC13, DMSO, DMF, et al.). The polymers exhibite excellent environmental stability, high electrical conductivity and electrochemical activity. The polymers have a attractive application potential as an electrode material.
