Singlet Transition

The absorption and emission spectra of 1,8-naphthalimide derivatives have been calculated by time-dependent density functional theory. Their lowest singlet transition states can be described as the promotion of electrons from the HOMO to the LUMO. Substituents on naphthalimic ring seldom extend the conjugation of the central naphthalimic system.
