Abstract
The spectral-luminescence properties, lasing ability, and time-resolved gain spectra of three morpholine derivatives of naphthalimide (substituted in position 4) in polar (ethanol and dimethylformanide) and nonpolar (diethyl ester and toluene) solvents are investigated. It is found that rotation of the morpholine group about the single bond connecting the group with the rest molecule takes place, which results in a shift of the gain spectrum towards the longwave region and decrease of the fluorescence quantum yield.
