Thermal and photoluminescence analysis of a methacrylic diester derivative of naphthalene-2,7-diol

The synthesis and thermal and optical properties of a new type of photoluminescent monomer of 2,7-bis[2-(2-hydroxy-3-methacryloyloxypropoxy)propoxy]naphthalene (2,7-NAF.PMEM) are presented. The chemical structure of 2,7-NAF.PMEM was confirmed by 1 H and 13 C NMR analysis and ATR-FTIR spectroscopy. Next, bulk copolymers were synthesized using two comonomers, methyl methacrylate and styrene. These monomers were chosen because of their good optical properties (high visible light transparency). The thermal properties of the new copolymers were studied by the TG/DSC/QMS-coupled method in an inert atmosphere. The UV–Vis absorption and luminescence spectra of the obtained polymers were registered and evaluated. The 510-nm luminescence band was observed independently of the kind of monomer and its concentration.
