The location of the “spacer–receptor” unit in a 4‐aminonaphthalimide fluorophore, which undergoes internal charge transfer in the excited state, is crucial for the suitability of the compound as a pH sensor. In studies of the pH dependence of the fluorescence of the regioisomers 1 and 2 , only 1 displayed desirable properties.
