successfully synthesized from their nitro-analogs in a rapid, simple, and highly efficient fashion employing a sodium sulfide/pyridine system as a reducing agent. In this research, classic and sustainable reduction methodologies including NH4HCO2/Zn and a choline chloride/tin (II) chloride deep eutectic solvent (DES) were also evaluated, showing degradation products, incomplete reactivity, and product
摘要 以硫化钠/吡啶体系为还原剂,以硝基类似物快速、简单、高效地合成了小系列的氨基低聚亚苯基亚乙烯基(OPV)。在这项研究中,还评估了经典和可持续的还原方法,包括 NH4HCO2/Zn 和氯化胆碱/氯化锡 (II) 低共熔溶剂 (DES),在所有情况下都显示出降解产物、不完全反应性和产物分离困难。直接的 Na2S/吡啶合成方案证明保持 OPV 主链的 EE 立体化学,该主链先前已通过 Mizoroki-Heck 交叉偶联反应组装。此外,还确定并讨论了光电特性,考虑在这些共轭系统中插入氨基作为未来构建可应用于超分子电子学、光收集和光催化的新型材料的贡献。图形概要
