摘要
合成了含有不同支链的三支结构的三嗪衍生物。测定了它们的线性吸收和发射性质以及双光子吸收和发射性质。发现D3h对称的八极分子与其结构相似的分子相比,有着更好的单光子和双光子吸收以及发射性能。
One tfi - branched molecules with different branches in each of them were synthesized, and their photophysical characteristics were investigated by UV -vis spectra, fluorescence spectra, two - photon excited fluorescence spectra. The optical properties of these two compounds were compared with those of their analogs that have complete D3h oetupolar symmetry, the resuks showed that the absent of complete octupolar symmetry of D3h resulted ined the great decline of single - photon absorptivity and single -photon excited fluorescence, as well as the two- photon exeitated fluorescence.
