摘　　要：以2-甲基蒽醌为原料,经氧化、还原、溴化和Heck偶联反应合成了一个新型的三苯胺支状化合物(AAn-G2),其结构经1HNMR,IR,MS(ESI)和元素分析表征。采用FL和UV-Vis研究了AAn-G2的线性、非线性光学和聚集态发光性能。结果表明:AAn-G2具有聚集态荧光增强和双光子吸收特性。AAn-G2在固体状态下的荧光强度是溶液状态的7倍。在THF溶液中,730nm泵浦下,双光子吸收截面达383GM。A novel triphenylamine-branching compound(AAn-G2) was synthesized from 2-methylanthraquinone by oxidation,reduction,bromination and Heck coupling reaction. The structure was characterized by 1 H NMR,IR,MS(ESI) and elemental analysis. The linear,nonlinear and aggregation state optical properties of AAn-G2 were investigated by FL and UV-Vis. The results showed that AAn-G2 displays aggregation-induced enhanced emission(AIEE) and two-photon absorption(TPA) properties. From solution to solid state,the fluorescence intensity increased by 7-fold. And under 730 nm excitation in THF solution,the TPA cross-section was up to 383 GM.
