The dynamic nature of the quenching of the fluorescence of 1,4\_amino-and hydroxy-substituted 9, IO-anthraquinone, with benzene, alkylbenzenes and other aryl hydrocarbons as quenchers, indicates formation of exciplexes, where charge transfer (CT) occurs from the S, (quencher) to the S, (fluoropliore
The fluorescence lifetime, rf, of 9-cyanoanthracene (9CNA) in the supercritical fluid (SF) of Xe (6.8 MPa at 293 K) is found to be 2.39 \_ 0.13 ns, which is much shorter than the 17.78 \_+ 0.43 ns measured in SF of CO 2. This large decrease in Tf is interpreted in terms of the vibronic-level-depende
