| Abstract: | We report herein an unprecedented example of a luminescent SmIII metal–organic framework (Sm‐MOF), in which both the visible and near‐infrared (NIR) emissions of Sm3+ ions are able to be sensitized by an excited‐state intramolecular proton transfer (ESIPT) ligand. Due to the solvent‐mediated interchange between enol and keto excited states of the ligand and subsequent energy transfer rate to Sm3+ ions, the luminescent decay lifetime of the Sm‐MOF can be tuned in different solvent‐grinding systems. |
