| 摘 要： | 比较了用稀土和白川催化体系,制备的70％顺式含量及全反式聚乙炔的拉曼光谱及其随激发光源波长的变化。报道了用稀土催化体系制备的可溶性聚乙炔的拉曼光谱。这些实验结果支持导致反式聚乙炔拉吏异常的主要原因是反式聚乙炔链段共轭长度分散的解释。

| Abstract: | Resonance Raman spectra and its dependence on the excitation photon energy of partially isomer ized and all trans-polyacetylene prepared by rare-earth catalyst were compared with that of polyacetylene prepared by Shirakawa's catalyst. Resonance Raman spectra have been reported firstly for soluble polyacetylene prepared by rare-earth catalyst. The observed results seem to support the consideration of that the observed Raman anomaly for trans-polyacetylene is originated from dispersion of conjugation length in polyacetylene chain. |
