A “super” photobase experiences a 14‐unit jump in pK_a from its ground to excited state as the result of photon absorption. In their Communication (DOI: 10.1002/anie.201806787), 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.

“超级”照片库的超快动力学

由于吸收了光子，“超级”光碱的p K _a从其基态跃迁到激发态会发生14个单位的跃迁。B.Borhan，M.Dantus和同事在其《交流》（DOI：10.1002 / anie.201806787）中报告了发现了一种能够从有机溶剂中提取质子的芴基光模块的发现，揭示了其分子间受激分子的超快动力学。状态质子转移过程。
