N-acylation was studied as a method for reducing the LUMO energy levels of benzodipyrrolidone-based polymers. The N-acylated polymers showed reduced LUMO levels and improved reversibility of reductive doping compared with N-alkylated polymers. This method may also apply in other conjugated polymers with lactam repeating units.
研究人员将 N-酰化作为降低苯并二
吡咯烷酮基聚合物 LUMO 能级的一种方法。与 N-烷基化聚合物相比,N-酰化聚合物的 LUMO 能级更低,还原掺杂的可逆性更好。这种方法也适用于其他具有内酰胺重复单元的共轭聚合物。
