摘要
本文合成了四个"芘"核化合物并进行了结构验证,同时本文还研究了不同"枝"及"枝"数的不同对"芘"核化合物的单、双光子荧光性质的影响。实验结果表明,随着"枝"数增加,共轭度的增加,所得化合物的单、双光子荧光强度明显增强。而在共轭度相同的条件下(共轭度:P-T1=P-B1,P-T3=P-B3),三苯胺结构的扭曲运动消耗了能量,以热的形式释放,使得三苯胺枝化合物的单光子荧光强度明显减弱。
Four ＂pyrene＂ derivatives were prepared and investigated. The properties of one photon-and two-photon-absorption were affected by different ＂branches numbers＂ and ＂branches＂ in ＂pyrene＂ core compounds. The results show that with the number of branches and conjugate degree increasing, one-photon-and two-photon-excitation fluorescence intensity is enhancing. In the same level of conjugate degrees （conjugate degrees. P-T1 = P-B1, P-T3 = P-B3）, the compounds luminous intensities decrease, which attributes to the structure distortion of triphenyl- amine.
