Studies on the Fluorescence Enhancement of Reverse Micelle on 2,3-Diaminophenazine

Abstract

Abstract: The effects of reverse micelle(AOT/n-octane) on spectral characteristics of 2,3-diaminophenazine (DAP), which was an oxidized product of o-phenylenediamine catalyzed by laccase, were investigated. It was shown that there was little effect on the absorption features of the product by AOT/n-octane. However the fluorescence of the product was greatly enhanced by AOT/n-octane, and the quantum yield was increased about 30-folds by AOT/n-octane. The effects of microenvironment on the fluorescent property of DAP and the mechanism of fluorescence enhancement in reverse micelle AOT/n-octane were also studied.
