直接芳基化法已被用于制备噻吩亚甲基羟吲哚（TEI）和3，3-双[[（2-乙基己基）氧基]甲基]-3，4-二氢-2H-噻吩并[3，4-B][1，4]二氧杂卓（ProDOT）的新型给体-受体共轭聚合物。该聚合物在中性状态下呈现蓝色色调，在0 V至+1.5 V的施加电位下具有明显的颜色-透射可逆电致变色切换，并且在近红外区域显示出高的显色效率（436-438 cm 2·C−1），在环境条件下具有约1-2 s的高切换速度。
Direct arylation methods have been used to polymerize thienylmethylene oxindoles (TEIs) and 3,3-bis[[(2-ethylhexyl)oxy]methyl]-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepin (ProDOT) for new donor-acceptor conjugated polymers. The polymers exhibited blue hues in neutral-state with distinct color-to-transmissive reversible electrochromic switching under applied potentials from 0 V to +1.5 V, and showed high coloration efficiencies (436–438 cm2·C−1) in near-infrared regions with high switching speeds around 1–2 s under ambient conditions.
