Polycyclic benzimidazole derivatives, an important class of compounds in organic electronics and photovoltaics, were prepared using a solvent-free “green” process based on heating carboxylic acid anhydrides and arylene diamines in the presence of zinc acetate in the solid state. Products were isolated and purified directly by train sublimation of the crude reaction mixtures. The reaction conditions
多环苯并咪唑衍生物是有机电子产品和光伏产品中的一类重要化合物,是使用无溶剂的“绿色”工艺制备的,该工艺基于在固态乙酸锌存在下加热羧酸酐和亚芳基二胺的方法。产物的分离和纯化是通过将粗反应混合物直接升华进行的。使用各种羧酸酐优化反应条件。还描述了这些材料的光学和电化学性质。
