| Abstract | Photophysical properties of some 4-alkylamino-N-alkyl-1,8-naphthalimides and 3-bromo-4-alkylamino-N-alkyl-1,8-naphthalimides in ethanol solution have been investigated. It was demonstrated that the bromine atom in a C-3 position alters their properties. The bromine derivatives have a lower quantum yield of fluorescence owing to the influence of the bromine atom on the polarization of naphthalimide chromophoric system. On the other case, the photodegradation of these derivatives is higher and the reaction of photodegradation follows a pseudo first order. (C) 2003 Elsevier Science Ltd. All rights reserved. |
