近年来，含呋喃的共轭低聚聚合物因其独特的性能和在有机电子领域的应用前景而重新受到人们的关注。本文为深入了解不同初始单体的呋喃- edot共聚物的电合成及其性质，对呋喃- edot单体5-（呋喃-2-基）-2,3-二氢噻吩[3,4-b][1,4]二恶英（EDOT-Fu）、5,7-二（呋喃-2-基）-2,3-二氢噻吩[3,4-b][1,4]二恶英（fu - edot）、2,5-二（2,3-二氢噻吩[3,4-b][1,4]二恶英-5-基）呋喃（EDOT-Fu）的合成及电聚合性能进行了研究。全面报道了不同单体对优化电条件下所得聚合物结构和性能的影响，并对其进行了系统评价。这些单体具有良好的蓝绿色光致发光性能，量子产率在0.5 ~ 40%之间，可作为合理设计荧光共轭体系的基础。在单体链中加入EDOT单元后，膜的起氧化电位在0.78 V-0.45 V之间，与聚呋喃相比，膜的光电性能得到了改善。所制得的共聚物具有呋喃与PEDOT结合的优势，具有更高的荧光性和更好的平面性，PEDOT具有透明性和优异的氧化还原稳定性。系统地研究了不同活性单体形成的共聚物薄膜的结构表征和性能，包括FT-IR、UV-vis、TG、荧光、表面形貌和电致变色性能等。
Most recently, conjugated oligo-/polymers containing furan have regained attention due to their unique properties and promising application in organic electronics. Herein, to acquire a thorough fundamental understanding of the electrosynthesis and properties of furan-EDOT copolymers from different initial monomers, the synthesis and electropolymerization performances of furan-EDOT monomers, namely 5-(furan-2-yl)-2,3-dihydrothieno[3,4-b][1,4]dioxin (EDOT-Fu), 5,7-di(furan-2-yl)-2,3-dihydrothieno[3,4-b][1,4]dioxin (Fu-EDOT-Fu), and 2,5-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)furan (EDOT-Fu-EDOT), were comprehensively reported and the effect of different monomers on the structure and properties of the resulting polymers obtained under optimized electrical conditions were systematically evaluated. The monomers exhibit good blue-green photoluminescence with quantum yields ranging from 0.5 to 40%, which may be used as building blocks for rational design of fluorescent conjugated systems. The onset oxidation potential ranged from 0.78 V-0.45 V with the incorporation of EDOT unit in monomer chain, thus leading to the facile electrodeposition of free-standing films with improved optoelectronic properties in comparison with polyfuran. The obtained copolymers featured the advantageous combination of polyfuran and PEDOT, such as higher fluorescence and better planarity of polyfuran, transparency and excellent redox stability of PEDOT. Structure characterization and properties of the as-formed copolymer films from different initiative monomers, including FT-IR, UV-vis, TG, fluorescence, surface morphology and electrochromic properties, etc., were systematically investigated and comparatively discussed.
