摘要
本工作合成了新型的２－吡唑啉类化合物：１－３－二苯基－４－（ｐ－硝基苄叉）－２－吡唑啉，研究了该化合物在室温及低温７７Ｋ时的稳态光物理行为，结果表明：在标题化合物分子中存在着两种电荷转移机制，其一是从Ｎ１→Ｎ２→Ｃ３→苯基，其二是从Ｎ１→Ｎ２→Ｃ３→Ｃ４→Ｐ－硝基苄叉，光激发下，两种电荷转移机制相互竞争，且具有不同的发光构象。
In this work,a new type of 2-pyrazoline compound,1,3-diphenyl-4-(p-nitrobenzylidene)-2-pyrazoline(TPP),was synthesized; and the steady-state photophysical behavior at room temperature and lower temperature( 77K ) of the compound were studied. Results indicate that there are two charge transfer mechanisms in TPP,one is from N1→N2→C3→phenyl group,the other is from N1→N2→C3→C4→p-nitrobenzylidene. When thecompound TPP is excited,two charge transfer mechanisms compete with each other,andhave different fluorescence emitting conformations.
