ESIPT (excited‐state intramolecular proton transfer) molecules have a unique four‐energy level cycle and excellent photophysical attributes. However, the introduction of ESIPT elements into the construction and modulation of Ln‐complexes remains unexplored. Here, the systematic construction and visible‐to‐NIR emission of different lanthanides with an ESIPT ligand is reported for the first time. Unique PL response to solvents, anions, and temperature was achieved in these Ln‐complexes. In particular, upon addition of F − into the suspension of an Eu‐complex, the emitting color changes from reddish to bluish, which will be applicable for simple and feasible F − sensing in living cells.
