title: [Spectroscopic properties of 7-hydroxyquinoline in polymeric matrices].
abstract: In this paper, the absorption and fluorescence spectra of 7-Hydroxyquinoline (7HQ) in the copolymer of methyl methacrylate (MMA) and methacrylic acid (MAA) monomers were observed. The influence of different matrices on the species of 7HQ and the excited state proton transfer effect were investigated. The results showed that, as the number of carboxylic group in the matrix was increased, the relative contents of different species of 7HQ should be changed and the excited state proton transfer effect of 7HQ was enhanced.
