In this study, a C3-symmetric star-shaped discotic mesogen has been reported based on an electron-deficient tris(triazole) central rigid core functionalized with three peripheral trialkoxyphenyl units. The mesogen exhibits an enantiotropic columnar hexagonal (Colh) phase that can sustain over a significant temperature range. When used in space-charge limited current (SCLC) devices, it showed ambipolar charge transport behavior with high electron mobility (μe) of 1.61 × 10-2 cm2 V-1 s-1 at ambient temperature. The finding is sufficiently significant to warrant their use in organic electronic devices. © The Royal Society of Chemistry.
