Me, myself, and dye : Core‐unsubstituted perylene bisimide dyes bearing a melamine hydrogen‐bonding unit link with cyanurates giving H‐ (red, see picture) and J‐aggregates (green). In solution the aggregates can interconvert on thermal treatment or by changing the stoichiometry. In solid films the green to red color change occurs upon scratching the surface.
