A simple naphthol‐based fluorescent receptor 1 was prepared and evaluated for its fluorescence response to heavy metal ions. Receptor 1 exhibits an ‘off‐on‐type’ mode with high selectivity in the presence of Zn 2+ ion. The selectivity of 1 for Zn 2+ is the consequence of combined effects of chelation‐enhanced fluorescence (CHEF), C = N isomerization and π–π stacking interaction between the two naphthalene rings.
