英文摘要：

A novel poly（amic acid） bearing oligoaniline pendants was designed and prepared. Fourier transform infrared spectroscopy（FTIR）, 1H nuclear magnetic resonance spectroscopy（1H NMR） and gel permeation chromatography（GPC） were used to characterize its structure. The prepared polymer displayed an interesting spectroscopic property and reversible electrochemical activity. The material shows satisfactory electrochromic properties with high contrast value, acceptable switching times and excellent coloration efficiency.
