Abstract
Electrochromic materials based on conducting polymers with pendant chromophores as well as their electrochromic properties are described. The conducting polymers described are polypyrrole, polythiophene, poly(3,4-ethylenedioxythiophene), poly(cyclopentadithiophene), and poly{1,4-bis[2-(3,4-ethylenedioxy)thienyl]benzene}. The chromophores described are viologen and perylenetetracarboxylic diimide. When the wavelength ranges of absorption of the conducting polymer and the chromophore are not overlapping, multiple electrochromism was achieved. When the wavelength ranges are largely overlapping, higher contrast was achieved. An easy method for prediction of the film thickness for maximum contrast of a given electrochromic material is also described.

전도성 고분자에 곁가지로 chromophore를 결합시켜 만든 다양한 전기 변색 물질과 그 특성을 소개하였다. 전도성 고분자로는 polypyrrole, polythiophene, poly(3,4-ethylenedioxythiophene), poly(cyclopentadithiophene), 및 poly{1,4-bis[2-(3,4-ethylenedioxy)thienyl]benzene}를 사용하고, chromophore로는 viologen과 perylenetetracarboxylic diimide를 사용한 경우에 대하여 설명하였다. 전도성 고분자와 chromophore의 변색 파장 범위가 다른 경우에는 변색의 다양성을 성취할 수 있었으며, 변색 파장 범위가 비슷한 경우에는 색대비를 높일 수 있다. 최대 색대비를 나타내는 필름의 두께를 쉽게 예측할 수 있는 방법도 설명하였다.
