Abstract

Abstract— The absorption and fluorescence spectra of two functional ionic detergents containing an indole chromophore have been studied as micelle probes and have been compared to the corresponding spectra of 1-methylindole. The quenching of the fluorescence of the probes by NO-2 and Co2+ has also been investigated. Based on the results obtained, it is concluded that 1-methylindole is associated with the surface of HDTBr micelles, whereas it is located in the interior of SDS micelles. The chromophore of the indole detergents is considered to be located in the interior of HDTBr and SDS micelles.
