Abstract 4‐methyl 2,6‐diformyl phenol ( DFP ) is widely used for constructing metal complexes as well an array of chemosensors. However, the detailed photophysical understanding in various media and states aggregation has not been explored. shows excellent dependence on solvent polarity to furnish varyingly emitting species, which were studied by steady state time resolved emission spectroscopy. In lower solvents from keto form, whereas polar aprotic protic a cumulative contribution locally excited enol anion form. solid state, was due presence aggregated forms undergoing ESIPT make it yellow emitter. could act ratiometric sensor detecting water THF ACN (LOD∼ 0.4%). neat water, detect Zn 2+ upto 7.05 × 10 −7 (M) change maximum green blue. coated filter papers utilized reversible optical ammonia vapor using UV light smartphone‐based application. The sensing materialized ease loss polar/protic medium NH 3 .
