| 摘 要： | 研究了对苯二甲酸乙二醇酯－己内酯共聚酯（ＴＣＬ）溶液和本体的荧光光谱。结果表明，此共聚酯的荧光光谱与聚对苯二甲酸乙二醇酯（ＰＥＴ）的荧光光谱有所差别。ＴＣＬ在稀溶液中能形成分子内缔合物。在ＴＣＬ本体同时出现较强的单分子荧光和缔合物荧光，ＥＴ含量较低的ＴＣＬ在室温下还能观察到较强的磷光谱带。

| Abstract: | In this paper, the fluerescent spectra of the ethylene terephthalate (ET)-caprolactone (CL) copolyesters (TCL) have been studied. The results indicated that the fluouescent spectra of TCL copolyesters were different from the fluorescent spectrum of PET. A emission at about 390 nm was proved from a intramolecular excimer or associatied ground state dimer of the ET monomeric units. In the TCL films, the monomer and excimer fluorescence were observed simultaneously. For the TCL with lower ET content. the phosphorescence with relatively higher intensity was also observed. |
