Abstract

Inside knowledge: UV/Vis (absorption spectrum depicted) and Raman data reveal the stabilization of the trans‐keto tautomer of 2‐(2‐hydroxyphenyl)benzothiazole (HBT) inside the nanosized FAU zeolite. The trans‐keto tautomer exhibits highly intensive fluorescence in the zeolite, as compared to the cis‐keto tautomer, which is formed in solution during the excited‐state intramolecular proton‐transfer (ESIPT) process.
