✦ Synopsis

In this article, the room-temperature solution fluorescence quenching of electron-deficient anthracenes such as 9-cyanoanthracene (CNA), 9,lO-dicyanoanthracene (DCNA), and 9,lOdichloroanthracene (DCLA) by polysilane copolymers was studied. The fluorescence quenching data was in conformity with the Stern-Volmer equation Fo/F = 1 + Ksv[Q], the

In the dioxane-H 2 O system, electron-transfer quenching processes have been observed between the excited 9-anthrylmethyl esters of butyric acid (A-4), caprylic acid (A-8), lauric acid (A-12) and palmitic acid (A-16) as fluorescence probes, and m-N-N-diethylaminophenyl esters of butyric acid (P-4),
