摘　　要： 研究了若丹明６Ｇ（Ｒ６Ｇ）在甲基丙烯酸甲酯（ＭＭＡ）、丙烯醚（ＡＡ）、甲基丙烯醚（ＭＡ）、丙烯腈（ＡＮ）和乙醇中以及在它们的二元和三元混合体系中的荧光行为，发现含ＡＮ的体系的荧光强度（Ｆ）比较接近于含乙醇体系的Ｆ值，并且ＡＮ的存在有利于减少荧光熄灭和内滤作用。找到了比较合适的单体混合比例，即ＭＭＡ：ＭＡ（ＡＡ）：ＡＮ＝１０：２：１时，体系的Ｆ和荧光量子效率接近于含同等量乙醇体系的Ｆ，并且其聚合物的玻璃化温度、硬度和透光率均接近于聚甲基丙烯酸甲酯的相应值。用ＡＮ取代乙醇作为染料增溶剂是可行的。 The fluorescence behavior of R6G in methly methyacrylate (MMA),methyacrylic acid (MA),acrylic acid (AA) and acrylonitrile (AN) system and their mixed system had been studied,and it was compared with that of ethyl alcohol-containing system.The presence of AN could reduce the fluorescence quenching and intrafiltering. With the optimum mononer proportion MMA : MA (AA):AN = 10: 2 :1 (mole), the fluorescence intensity and fluorescence quantum efficiency nearly as high as that of ethyl alcohol-containing system. Also ,the glass transition temperature,hardity and transparancy were almost the same as that of PMMA,The results show that with AN as the substitution of ethyl alcohol is possible.
