摘要: 研究了反相胶束介质丁二酸双(2-乙基己基)酯磺酸钠(AOT)/正辛烷(n-octane)对漆酶催化氧化邻苯二胺的产物2,3-二氨基吩嗪(DAP)光谱性质的影响.试验表明,AOT/n-octane对DAP吸光性质稍有增敏作用,而对其荧光具有强烈的增敏作用,使DAP荧光量子产率提高近30倍,并进一步研究了微环境对荧光性质的影响和反相胶束介质AOT/n-octane对DAP荧光的增敏机理.

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.

Key words: Reverse micelle, 2,3-Diaminophenazine, Fluorescence enhancement, Molecular spectrum
