A “super” photobase experiences a 14‐unit jump in p K a from its ground to excited state as the result of photon absorption. In their Communication on page 14742 ff., B. Borhan, M. Dantus, and co‐workers report the discovery of a modular fluorenyl photobase capable of proton abstraction from organic solvents, unveiling the ultrafast dynamics of its intermolecular excited‐state proton transfer process.
