Effective Hole and Electron Transport in Solution-Processable Nanoscale Films of a Deep-Green Dye exhibiting Room-Temperature Columnar Mesophases

Abstract

To evolve liquid crystals towards efficient nano-electronics, we report oxadiazole-functionalized anthraquinones showing roomtemperature columnar rectangular mesophases. Exhibiting nearly temperature-independent ambipolarity with maximum hole and electron mobilities in order of 10 -4 cm 2 V -1 s -1 and 10 -3 cm 2 V -1 s -1 , repectively, it is a pioneering study on solution-processable charge-carrier mobilities of this class of deep-green dyes.
