Novel blue-light-emitting polymers containing the blue chromophore 9,10-di(2-naphthyl)anthracene and a flexible spacer group were designed and synthesized via the Suzuki coupling reaction. The polymers show excellent thermal stability and solubility. Absorption and emission spectra indicate that the active chromophores in the polymers are 9,10-di(2-naphthyl)anthracenes. Polymers show blue photoluminescence in solution and solid state. Blue light emission was obtained from single-layer LED devices.
