Highly Soluble Ambipolar anti ‐Perylene‐3,4 : 9,10‐bis(benzimidazole)s Stabilize a Room‐Temperature Columnar Hexagonal Phase

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.
