The synthesis of a new blue fluorescent bis(1,8-naphthalimide) has been described and its basic photophysical characteristics have been investigated in organic solvents of different polarity. The detection of protons and different metal cations (Ag+, Cu2+, Co2+, Ni2+, Fe3+ and Zn2+) with the new compound has been investigated by the use fluorescence spectroscopy.
