Dioxyheterocycles, particularly 3,4-ethylenedioxythiophene (EDOT), have proven to be useful building blocks for conjugated materials targeting various applications. The 3,4-phenylenedioxythiophene (PheDOT) unit is similar to the EDOT unit in terms of planarity and steric interactions, but has different electronic properties because of the attached phenyl ring. This unit has been incorporated into soluble alternating copolymers for the first time via direct (hetero) arylation polymerization (DHAP). These polymers are effective electrochromes with vibrantly colored charge neutral states and colorless, transmissive oxidized states. Spray cast films are highly stable to redox switching, showing only a 1% decrease in contrast after 2000 switches without film encapsulation.

通过直接（杂）芳基化聚合反应生成的可溶性苯二甲氧基噻吩共聚物：有机电子产品的再生单体†

二氧杂环，特别是3，4-亚乙二氧噻吩（EDOT），已被证明是用于靶向各种应用的共轭材料的有用的结构单元。3,4-苯二甲氧基噻吩（PheDOT）单元在平面性和空间相互作用方面与EDOT单元相似，但由于连接了苯环，因此具有不同的电子特性。该单元首次通过直接（杂）芳基化聚合反应（DHAP）掺入可溶性交替共聚物中。这些聚合物是具有鲜艳颜色的电荷中性态和无色的透射性氧化态的有效电致变色。喷雾流延膜对氧化还原转换非常稳定，在不进行薄膜封装的情况下，经过2000次转换后，对比度仅降低了1％。
