Facile Synthesis of Lowsubstituted DBN as Discotic Liquid Crystals

【摘要】:正Disc-like molecules with a rigid, flat core surrounded by flexible side groups pointing outwards, can form columnar thermotropic mesophases. Potential applications of such compounds in conducting, photoconducting systems, optical data storage, light emitting diodes, photovoltaic solar cells, gas sensors, and other devices have been envisaged. Alkoxysubstituted dibenzo[fg,op]naphthacenes (DBN) are one main group of discotic liquid crystals. Lowsubstituted DBN derivatives could form more ordered columnar mesophase due to less steric hindrance of the
