Irradiation of 4,N-dibutyl-1,8-naphthalimide resulted in one major photoproduct. Our starting material and 20 micro-liters of n-butylamine were irradiated. 4-amino-N-butyl-1,8-naphthalimide was created under conditions of water, ethanol, and 1X PBS buffer. Modifying the solvent concentration, time intervals, buffer pH, and adding n-butylamine all produced the same, single photoproduct. Proposed mechanisms will be presented and discussed.
