A butadiene-styrene copolymer of low styrene content (5%, Wt.) has been characterized by 1H NMR to have only isolated styrene units on the chain. The fluorescence spectra of the sample in dilute solutions of a good solvent (dichloroethane) at 25-26℃ showed monomer fluorescence only. Changes of the. fluorescence spectra from a good solvent to poor solvents (dichloroethane-methanol mixture), and from dilute to concentrated solutions up to the solid film confirmed that excimer formation exists between nonadjacent chromophores in the chain and between interchain chromophores. Com-parision of the spectra obtained from a dilute 8-solution and solid film gave us an estimation of the relative importance of the intrachain excimer interaction and interchain excimer interaction in the solid sample studied. These results may help us to visualize the interpenetration and entanglement of polymer coils during transition from a dilute solution to a concentrated one and to a solid polymer.

本文报导一种低苯乙烯含量(5%,Wt.)的丁二烯-苯乙烯共聚物,经~1H NMR证明其分子链上不存在相邻苯乙烯单元。荧光光谱结果表明,它在良溶剂(二氯乙烷)的稀溶液状态下只呈现单分子荧光。从良溶剂-θ溶剂(二氯乙烷-甲醇体系)及稀溶液-浓溶液-固体之荧光光谱的变化,证明形成了链内非近邻生色团之间和链间生色团之间的激基缔合物(Excimer)。从固体与θ溶剂的激基缔合物荧光的比较,还可区分链内非近邻和链间苯环形成激基缔合物对荧光强度的贡献。这一结果对阐明高分子链内非近邻和链间激基缔合作用提供了新的证据,并有助于了解高聚物本体中相互穿透、相互缠结的无规线团的形态。

In this paper, an experiment research of absorption spectra, fluorescence spectra, fluorescence decay and fluorescence excitation spectra for molecules HpD-01 and HpD-02 (01 and 02 are sample numbers) have been reported.The results have been given:(1) The peak positions of fluorescence excitation spectra coincide with ones of absorption spectra in the same resolvent, but their relative amplitudes are still different.(2) The fluorescence and absorption spectra are related with the environment(resolvent), but the fluorescence decay time is not.(3) The fluorescence spectra of molecule HpD-01 are similar with ones in earlier report of America, and the HpD-02's are close to the latest results of Japan.These results maybe benefit the clinical diagnosis and cure of cancer.

本文报导了HpD-01(01为实验样品编号,下同。)和HpD-02分子的吸收谱、荧光谱、荧光衰碱和荧光激发谱的实验研究。结果表明在同一种溶剂中荧光激发谱和吸收谱的各峰值位置一致,但荧光激发谱的各峰相对幅值与吸收谱的比是不同的。荧光激发谱和吸收谱同HpD的周围环境(溶剂)关系较大。荧光衰减时间和文内选取的溶剂关系不明显。发现HpD-01号分子的荧光激发谱同美国早期报导的近似,HpD-02号分子的结果同日本近年来报导的相近。文内对结果进行了讨论,指出,荧光激发谱的研究对激光用于临床诊治癌症具有实际意义。
