联有含氮茋的2-吡唑啉化合物的光物理行为

The Photophysical Behavior of 2-Pyrazoline with Azastilbene

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。

In this work, a new kind of 2-pyrazoline compound with azastilbene on position 5 has been synthesized. The photoinduced cis-trans isomerization and its mechanism have also been studied. Results indicate that the rate for the photoisomerization reaction of the title compound depends strongly on the polarity of solvents used, and the photoisomerization reaction led to increase of the fluorescence intensity of this compound with increase of irradiation duration.
