| 英文摘要 | Steady state fluorescence and fluorescence decay of a series of monosubstituted biphenyl containing side. chain liquid crystalline polyacetylenes with different lengths of spacers were investigated. For comparison, a monomer was selected as a model compound. Steady state fluorescence spectra elucidated that the polymers and the monomer showed single fluorescence emission arising from the biphenyl group on the side chain. With decreasing the length of the spacer, the fluorescence intensity of the polymer decreased accordingly. The fluorescence decay showed that the decay of the monomer could be fitted to be a single. exponential decay, while that of the polymers should be fitted to be a triple. exponential decay, which may be originated from the local high concentration induced quenching and the rotational restriction of the side. chain biphenyl groups. Solvent effects illustrated that the interaction between the solvents and the biphenyl groups strengthened with increasing the polarity of the solvents. |
