Organic electrochromic materials change color rapidly under applied potential. A butterfly-shaped compound, 5,5',-5″,-5'″-(thieno[3,2-b]thiophene-2,3,5,6-tetrayl) tetrakis-(2,3-dihydrothieno[3,4-b][1,4]dioxine) (t-EDOT-TT) is synthesized for the first time and polymerized at different potentials via electropolymerization technique. By applying different polymerization potentials, the optical and electrochromic properties of this newly synthesized polymer can be tuned. Owing to the dependence of functional group position in the polymer structure on the redox potential, this polymer can be utilized in very interesting organic optoelectronic applications.
有机电致变色材料在施加电势时会迅速变色。首次合成了一种蝴蝶形化合物5,5',-5″,-5'″-(噻吩并[3,2-b]噻吩-2,3,5,6-四亚基)四(2,3-二氢噻吩并[3,4-b][1,4]二恶英)(t-EDOT-TT)，并通过电聚合技术在不同电势下进行聚合。通过施加不同的聚合电势，可以调节这种新合成聚合物的光学和电致变色性能。由于聚合物结构中官能团位置对氧化还原电势的依赖性，这种聚合物可用于非常有趣的有机光电子应用中。
