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。
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.
