Photobase‐Driven Excited‐State Intramolecular Proton Transfer (ESIPT) in a Strapped π‐Electron System

We report a new design strategy for an excited‐state intramolecular proton transfer (ESIPT) fluorophore that can be used in acidic media. A photobasic pyridine‐centered donor‐acceptor‐donor‐type fluorophore is combined with a basic trialkylamine “strap”. In the presence of an acid, protonation occur...
