Butterfly‐like Shape Liquid Crystals Based Fused‐Thiophene as Unidimensional Ambipolar Organic Semiconductors with High Mobility

International audienceButterfly-like mesogens based on benzodithiophene, benzodithiophene-4,8-dione and cyclopentadithiophen-4-one core moieties were efficiently synthesized by the Suzuki-Miyaura/Scholl reactions' tandem. Depending on the core nature and radial aliphatic chains number, they selforganize into columnar hexagonal mesophase, possess solvent-gelling ability, emit light in the visible range, and display hole-transport performances. In particular, the mesogen with benzodithiophen-4,8dione core shows ambipolar charge carrier transport with both high electron and hole mobility values
