含芳香基之鄰苯二甲醯亞胺之合成與螢光性質研究

目前新興的聚集誘導放光 (aggregation induced emission, AIE) 的發光材料已經知道可以廣泛的應用，但是已被發表的具有聚集誘導放光性質的材料種類仍舊稀少，純有機化合物的材料又特別少見。首先，在本篇論文中，我們將會詳細的介紹聚集誘導放光的放光機制，並且我們實驗室也開發出一系列新型具有聚集誘導放光性質的發光材料，即含芳香基之鄰苯二甲醯亞胺化合物。我們以簡單的合成途徑將化合物合成出來，並且將這些合成出來的含芳香基之鄰苯二甲醯亞胺化合物，做螢光性質（吸收光譜、放射光譜以及量子產率）的分析。這一系列的化合物包含了不同的取代基 (例如：拉電子基、推電子基)，我們將探討這些不同取代基對於放光或者是在模擬固態時的堆疊情形是否具有影響性，以及多種芳香基團對於其螢光性質的影響。本文中我們將化合物溶於二氯甲烷與乙醇的溶液中，來探討當這些化合物在分散和聚集時的放光情形以及其量子產率。

New aggregation induced emission materials have a wide range of applications and have been confirmed, but the AIE type of material has been published is still scarce. The material of pure organic compounds are particularly rare. Therefore, in this thesis, we have developed a series of new luminescent materials with AIE nature, that is tetra-phenyl or biphenyl N-substitute phthalimide, and used the simple route to do the synthesis. We also measure the fluorescence properties of the synthesized phthalimide compounds containing aromatic group, with the measure containing the absorption spectrum, emission spectrum and quantum yield. We also have compared the fluorescence properties in different substitute, containing various kinds of aromatic ring and the different functional groups. In this thesis, we try to explore the impact on the compounds properties in the polar and nonpolar solvents.
