We present two ways of fast and easy immobilisation of a naphthalimide chromophore with a pH-sensor function. The immobilised dyes exhibit absorbance and emission in the visible spectral range, large Stokes' shift, fluorescence properties that are comparable to their water-soluble form, and full reversibility in pH response.
