A new series of highly soluble perylene anti-bis(4,5-dialkoxybenzimidazole)s bearing branched flexible chains stabilizing room temperature columnar hexagonal phase and with balanced ambipolar charge carrier mobility is reported for the first time. Only the anti isomer was successfully separated and characterized. These compounds have a high extinction coefficient, small optical band gap and wide absorption range, thus making them a promising class of ambipolar organic semiconductors capable of self-organizing.
首次报道了一系列新型的高溶解性苝双（4,5-二烷氧基苯并咪唑），其带有支化柔性链，可稳定室温柱状六方相，且具有平衡的双极性电荷载流子迁移率。仅成功分离并表征了反式异构体。这些化合物具有高消光系数、小光学带隙和宽吸收范围，因此使其成为一类有前景的能够自组装的双极性有机半导体。
