| 摘 要： | 通过观测７－羟基喹啉（７ＨＱ）在甲基丙烯酸甲酯（ＭＭＡ）和甲基丙烯酸（ＭＡＡ）以不同配比共聚的基质中的吸收光谱和荧光光谱，研究基质对７ＨＱ各物种相对含量的变化和对７ＨＱ激发态质子转移的影响。结果表明基质中羧基数目增加，可使７ＨＱ各物种的相对含量发生变化，并有利于７ＨＱ发生激发态质子转移。

| Abstract: | In this paper,the absorption and fluorescence sp ectra of 7-Hydroxyquinoline (7HQ) in the copolymer of methyl methacrylate (MMA) and methacrylic acid (MAA) monomers were observed.The influence of different ma trices on the species of 7HQ and the excited state proton transfer effect were i nvestigated.The results showed that,as the number of carboxylic group in the mat rix was increased,the relative contents of different species of 7HQ should be ch anged and the excited state proton transfer effect of 7HQ was enhanced. |
