Di‐ ortho ‐fluoroazobenzene Functionalized Discotic Nematic Liquid Crystals as Soft Ambipolar Semiconductors

We report two discotic nematic (N D ) liquid crystals (LCs) based on di‐ ortho ‐fluoroazobenzene units tethered to hexaalkynyl and pentaalkynyl benzene cores. The molecular design combines photoresponsive azobenzene motifs with discotic architectures to promote charge transport in the nematic phase. Notably, space‐charge‐limited current measurements reveal that compound 1 exhibits ambipolar charge transport with carrier mobilities of the order of 10 −3 cm 2 V −1 s −1 . These results highlight di‐ ortho ‐fluoroazobenzene functionalized discotic nematics as promising soft semiconducting materials.
