以三聚茚為主體之三維衍生物合成及其在超分子應用探討

Abstract

在本論文中，我們在三聚茚5, 10 ,15 號位置上修飾上苯環取代基創造出三維的架構中間體後，利用其獨特三維結構進行數種不同領域的衍生研究：籠狀分子(CM、CT)；有機凝膠分子(TPDA、TMDA)；電子予體超分子(TPBT、TMBT)。 籠狀分子方面我們在此選用不同的苯環衍生物當作 「蓋子」 鎖住中間體的構型，形成獨特的「奈米籠」並觀察其X-Ray 單晶以及光物理性質；有機凝膠分子設計則是在中間體上修飾上具有氫鍵作用力官能基及長碳鏈，並利用雙共軛螢光顯微鏡、掃描式電子顯微鏡及穿透式電子顯微鏡等儀器觀察其與溶劑交互作用形成之微結構，並探討微結構背後形成機制；超分子應用方面我們在中間體上帶上多電子的「手臂」，期望可以與碳六十有良好的超分子作用，形成良好的予體—受體組合。

In our previous contribution, we reported a unique 3D skeleton based on truxene moiety. The success of synthesizing such skeleton provides us with convenience to realize the structural diversity of 3D derivatives through orthogonally and distinguishably modifiable sites. As a result, such a 3D structure would offer various derivatives with diverse functionalities. Herein, we utilize this 3D functionalized “body' (a covalent template) to couple with suitable planar “caps' to achieve quantitative formation of C3 symmetrical nanocages. Furthermore, we functionalized this central core to achieve the 3D architecture organogelators. To the best of our knowledge, there is no organogelator based on 3D skeleton design. Therefore, the microstructure and the gelation mechanism of these gelators are very intriguing. And then we developed this 3D structure as a “molecular claw', expecting it could have good interaction with bulky ball.
