Chemiluminescent characteristics of blue light-emitting polymeric fluorophores containing distyrylarylene units

Distyrylarylene-containing model compounds, 4,4'-bis[2-(4-methoxyphenyl)-2-phenylvinyl]benzene (1) and 4,4'-bis[(3,4,5-trimethoxyphenyl)vinyl]benzene (2), and polymers (3)-(6) were synthesized for a chemiluminescence fluorophore. The UV absorbance, fluorescence excitation and emission, photoluminescence as well as the chemiluminescence characteristics of the model and polymeric fluorophores were measured. Sodium benzoate catalyzed reaction of TCPO with hydrogen peroxide produced a strong chemiluminescent blue light emission with 433 similar to 440nm in the presence of a fluorophore. The wavelength of chemiluminescence light was similar to that of photoluminescence and fluorescent emission. The intensity of chemiluminescent emission showed a 5400 similar to 5000 mcd/m(2) after mixing the sample and 1200 mcd/m(2) and 28-30 mcd/m(2) alter 1 hr and 30 min, respectively.
