    摘要: 本論文主要在於探討異參茚并苯與其衍生物ITF的合成與光化學及熱化學性質。 先前文獻中有關異參茚并苯的論文報導僅有一篇,且其合成之產率並不高,我們則意外地以茚與2-溴吡啶在鈀金屬催化下合成出化合物異參茚并苯,但產率僅有9%,因此提升其產率成為我們的實驗目標之ㄧ。此外,由於其異構物參茚并苯具對稱性的C3結構,近年來引起了廣泛的研究與應用,因此我們希望比較不對稱的異參茚并苯與其在物性上不同之處,例如在作為發光材料應用上。因此我們合成異參茚并苯衍生物ITF來進ㄧ步與參茚并苯衍生物T1-T4作比較。 結果顯示化合物ITF與化合物T4幾乎具有相同的螢光波長範圍,類似的電化學與熱化學穩定性,因此有潛力可作為一藍光的發光材料。 This thesis reports the synthesis of isotruxene, and the synthesis, fluorescence and thermal properties of its derivative ITF. There is currently only one paper in the literature related to the synthesis of isotruxene, and its yield was low. We happened to synthesize isotruxene with indene and 2-bromopyridine under palladium-catalyzed condition, but its isolated yield is only 9%. Therefore one of our research goal is to promote its yield. In addition, its isomer truxene, which has a symmetrical C3 structure, has attracted much attention in recent years. Therefore, we would like to compare the physical properties of the derivatives of truxene and isotruxene, for example, in terms of their luminescent behavior. We have thus synthesized the isotruxene derivative ITF and compared with the truxene derivatives T1-T4. The results showed that compound ITF and compound T4 have nearly the same fluorescence emission energies, thermal and electrochemical stabilities, which might prove of value being a blue emitter.
