Ion-responsive fluorescent compounds. 4. Effect of cation binding on the photophysical properties of a coumarin linked to monoaza- and diaza-crown ethers
TL;DR: In this paper, the photophysical changes upon complexation with alkali and alkaline-earth metal cations can be described in terms of enhancement of the intramolecular charge transfer in the coumarin dye.

The UV–visible absorption and fluorescence of some substituted 1,8-naphthalimides and naphthalic anhydrides
Michael S. Alexiou,Vasiliki Tychopoulos,Shohreh Ghorbanian,John H. P. Tyman,Robert G. Brown,Patrick I. Brittain +5 more
Abstract: A number of substituted 1,8-naphthalimides and naphthalic anhydrides have been prepared and their absorption and fluorescence properties in absolute ethanol have been determined. In the absence of an alkylamino substituent in the naphthalene ring, the compounds are colourless and weakly fluorescent. In the presence of such a substituent they become yellow and frequently fluoresce strongly with quantum yields of the order of 0.8.

Solvent dependence of the inhibition of intramolecular charge-transfer in N-substituted 1,8-naphthalimide derivatives as dye lasers
E. Martin,Rosa Weigand,A. Pardo +2 more
TL;DR: In this article, an intramolecular charge transfer (CT) was used to inhibit the fluorescence and laser emission in the derivatives with an amino terminal group in the side chain, and a high lasing efficiency in the green-blue zone of the spectrum was obtained with a N 2 pulsed laser.
