In contrast to chemical intuition fully conjugated aromatic compounds can be rapidly synthesized and crystallized in nothing but high‐temperature water. In their Communication on page 12270 ff., M. M. Unterlass et al. report the hydrothermal crystallization of indigo, pentacenetetrone, and perinone, as well as the direct synthesis of perinone from naphthalene bisanhydride and o ‐phenylenediamine in high‐temperature water without the need for co‐solvents or catalysts. The picture shows crystals and molecules of the red pigment trans ‐perinone surrounded by water.
