Abstract
Polyester fluorophores containing red and blue light-emitting chromophore units were prepared by copolycondensation of perylene tetracarboxydiimide and diphenyl anthracene derivative with sebacoyl chloride for the chemiluminescence. The properties of fluorophore polymers were studied by UV-Vis spectrophotometric, photoluminescent and chemiluminescent investigation. The intensities of UV-Vis absorbance, photoluminescence and chemiluminescence spectra appeared to systematically increase as the content of two monomers. The sodium salicylate-catalyzed reaction of bis(2-carbopentyloxy-3,5,6-trichlorophenyl)oxalate with hydrogen peroxide provided a strong chemiluminescent light changing from red to blue according to the content of two chromophore units; these were similar to the photoluminescent spectra. The chemiluminescent intensity was decayed biexponentially, but the glow of chemiluminescence maintained more than 24h and was visible with the naked eye.
