Discotic liquid crystals have emerged as very attractive organic semiconductors due to their high degree of ordering and self‐healing capacity. Quantum‐chemical calculations that describe the main parameters governing the charge‐transfer processes in these systems at the molecular level are reported. The concepts are illustrated by considering columns made of triphenylene molecules and derivatives (see Figure).
