Two novel triangle‐shaped discotic graphenes with swallow‐like alkyl tails are synthesized; these discotic graphenes allow facile purification, control over thermotropic properties, and solution fabrication into efficient photovoltaic devices. The unique molecular design results in an extremely broad liquid‐crystalline range and the ability to self‐heal at low processing temperatures, which improves the performance of photovoltaic cells.
