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 room-temperature columnar rectangular mesophases. Exhibiting nearly temperature-independent ambipolarity with maximum hole and electron mobilities on the order of 10⁻⁴ cm² V⁻¹ s⁻¹ and 10⁻³ cm² V⁻¹ s⁻¹, respectively, it is a pioneering study on solution-processable charge-carrier mobilities of this class of deep-green dyes.
