heterocyclic ring of N-aryl-4-chloro-1,8-naphthalimides, reported to be resistant to nucleophilicattack, reacts with primary amine nucleophiles at room temperature to give 4-chloro-N-alkyl-1,8-naphthalimides. The reaction is first order in the naphthalimide. The Hammett plot is linear (R2 0.996) with a large positive slope (+3.0), consistent with substantial negative charge development at nitrogen in the

An efficient and functional group tolerant route to access hydroxy 1,8-naphthalimides has been used to synthesise a range of mono- and disubstituted hydroxy-1,8-naphthalimides with fluorescence emissions covering the visible spectrum. The dialkoxy substituted compounds prepared possess high quantum yields (up to 0.95) and long fluorescent lifetimes (up to 14 ns). The method has been used to generate
