TL;DR: In this paper, the authors performed ultrafast pump-probe studies of room-temperature solutions of 3-hydroxyflavone (3-HF) and some 4-substituted derivatives.

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.

TL;DR: Anomalous fluorescence behavior was reported for the 4′- N, N -dimethylamino derivatives of 3-hydroxy- and 3-methoxy-flavone as mentioned in this paper.

TL;DR: In this article, the formation of an exciplex between the naphthalimide ring and the distal dimethylamino group which is stabilised by electron transfer is described.

TL;DR: In this article, the azoles 2-(2 0 -hydroxyphenyl)oxazole (HPO) and 4-methylthiazole (HPT) have been synthesized and studied in order to compare their photophysical characteristics.
