合成了一种在（5）位上联有含氮的2-吡唑啉化合物，研究了该化合物分子所呈现的光敏顺-反异构化现象，并对其机理进行了考察，研究结果表明：具电子转移性质的该化合物顺-反异构化反应速率强烈的依赖于溶剂的极性。同时，光敏异构化还导致了该吡唑啉化合物荧光发射强度随光照时间而增大的有趣结果。
A novel 2-pyrazoline compound containing nitrogen at the (5) position was synthesized. The photo-cis-trans isomerization phenomenon of the compound was studied and its mechanism was investigated. The results show that : The rate of cis-trans isomerization of this compound with electron-transfer properties strongly depends on the polarity of the solvent. At the same time, photoisomerization also led to the interesting result that the fluorescence emission intensity of the pyrazoline compound increases with the illumination time.
