Abstract
New conjugated and non-conjugated alternating block copolymers containing 9,10-diphenyl-2-chloroanthracene moieties in the main chain were synthesized via Williamson synthesis for the blue chemiluminescent fluorophore. UV-vis absorption and luminescent characteristics including chemiluminescence were measured and compared with model fluorophore 9,10-bis( p-methoxyphenyl)-2-chloroanthracene. Polymers displayed blue photoluminescence in solution with maximum around 430 nm. Tetramethyl ammonium salicylate-catalyzed reaction of hydrogen peroxide with bis(2-carbopentyloxy-3,5,6-trichlorophenyl)oxalate produced a strong chemiluminescent blue light emission with wavelength of 440 nm in the presence of the polymeric fluorophore. The chemiluminescent intensity decayed exponentially and the glow of chemiluminescence maintained more than l2 h and was visible with naked eye.
