可以用乙醇和正丁醇等简单醇类加工的有机电活性材料非常受欢迎，因为这些溶剂可以来自生物质，对人类和环境健康的危害较小。在这里，我们报道了通过可持续的直接芳基化聚合(DARP)方法合成的第一类聚(3-烷基胺基噻吩类)(P3AAT)，该方法可以使用绿色、可持续的溶剂进行加工。P3AAT的合成史无前例地展示了DARP的优越性，因为用这种方法只需三个简单的步骤就可以很容易地制备出MN高达15.4 kDa的P3AAT，产率高达90%。叔胺poly(N-hexyl-N-methylthiophene-3-carboxamide-2，5-diyl)(P1)在绿色溶剂乙醇、正丁醇和苯甲醚中具有良好的溶解性。在正丁醇中处理P1可以提供与二氯苯相当的空间电荷限制电流(SCLC)空穴迁移率和相称的光物理性质。还有，美国证券交易委员会。
Organic electroactive materials that can be processed using simple alcohols, such as ethanol and 1-butanol, are highly desired, since these solvents can be sourced from biomass and present lower hazards for human and environmental health. Herein, we report the first class of poly(3-alkylamidethiophenes) (P3AAT) synthesized via the sustainable method of direct arylation polymerization (DArP) that can be processed using green, sustainable solvents. The unprecedented synthesis of P3AAT reveals the superiority of DArP, as P3AAT can be readily prepared in only three simple steps with an Mn of up to 15.4 kDa and yields of up to 90% exclusively with this methodology. The tertiary amide, poly(N-hexyl-N-methylthiophene-3-carboxamide-2,5-diyl) (P1), has excellent solubility in the green solvents ethanol, 1-butanol, and anisole. Processing of P1 in 1-butanol is shown to provide comparable space-charge-limited current (SCLC) hole mobility versus dichlorobenzene and commensurate photophysical properties. Also, the sec...
