The cover shows novel triangle‐shaped discotic graphenes that are substituted by swallow‐like alkyl tails and allow facile purification, control over thermotropic properties, and solution fabrication into efficient photovoltaic devices. Xinliang Feng, Wojciech Pisula, Klaus Mullen, and co‐workers report on p. 2684 that this 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.
