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.

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 the case of polymethylene-bis-β-naphthoates, the excimer fluorescence intensities are related to methylene chain lengths. The fluorescence intensity of the one with trimethylene chain is the strongest. In the case of substituted bis-β-naphthyl alkanes, by introducing electron-attracting...

A series of polymethylene-bis-β-naphthoates and bis-β-naphthyl alkanes and their derivatives have been synthesized and their fluorescence spectra have been studied.Intramolecular excimer formations have been observed in all cases. In the case of polymethylene-bis-β-naphthoates, the excimer fluorescence intensities are related to methylene chain lengths. The fluorescence intensity of the one with trimethylene chain is the strongest. In the case of substituted bis-β-naphthyl alkanes, by introducing electron-attracting groups in the side chain, the electron densities of the two naphthalene rings become unequal. The λ_(max) values of the fluorescence emissions of the intramolecular excimers are blue shifted in comparison with the unsubstituted 1, 3-bis-β-naphthyl propane. The λ_(max) values of the excimers remain unaltered, but the I_E/I_2 values decrease with the increase of solvent polarity. So that, their properties shown do not completely resemble that of the typical excimers nor that of the typical exciplexes.

本文报道几种双—β—萘甲酸多次甲基二醇酯及双—β—萘基烷烃次甲基链上被极性基团取代的衍生物的合成及其荧光谱。结果表明,它们都能形成分子内激基缔合物,对于双—β—萘甲酸多次甲基二醇酯来说,其分子内激基缔合物的荧光强度与链长有关,以三次甲基链为最大。对于双—β—萘基烷烃取代衍生物来说,由于吸电子基团的引入使两个萘环的电子云密度不等,它们所形成的分子内激基缔合物的荧光峰都比未取代的1,3—双—β—萘基丙烷有所蓝移。在极性溶剂乙腈中其分子内激基缔合物的荧光峰的位置虽然不变,但I_E/I_2值则有所降低,表现出既不完全与激基缔合物相同,又不完全与激基复合物相同的性质。

The fluorescence spectra of a series of polymethylene bis (β-naphtboate) solution of various concentrations have been studied in an attempt to distinguish between intra- and inter-molecular excimers which are observed in all cases.A normalized method of plotting the fluorescence spectra was used, in which the ethyl-β-naphthoate was chosen as the standard for comparison.
