摘要：

A series of fluorescent copolyesters were prepared by melt polycondensation reaction using dimethyl terephthalate, butanediol, propylene glycol and 1, 6, 7, 12-tetrachloroperylene tetracarboxylic acid dianhydride(TTAD) as monomer. The influence of tetrachlorophthalic anhydride content on the fluorescence performance of the copolyesters was studied. The chemical structure and fluorescence quantum efficiency of the copolyesters were characterized by UV spectrophotometer, nuclear magnetic resonance spectrometer and fluorescence spectrophotometer. The results show that the copolyesters have high brightness and high fluorescence quantum yield. With the increase of TTAD content, the copolyesters exhibit different fluorescence from yellow-green to orange-red. The TTAD in copolyesters does not undergo fluorescence aggregation quenching in the copolyesters. © 2021, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
