Incorporation of pyrimidine fluorophores into poly(methylmethacrylate) polymer structures

摘要

Three polymethyl methacrylate based copolymers bearing arylvinylpyrimidine chromo-phores have been synthesized in four steps. Spectral properties of the copolymers have been studied in solution, powder and thin films and compared with the corresponding free chromophores. The copolymers exhibit strong emission solvatochromism and act as polarity sensors. They also exhibit halochromism: when adding acid, a bathochromic shift is observed in absorption whereas a red-shifted fluorescence is observed with increased intensity for the methoxy-substituted macromolecule.
