中文摘要
組合式化學的發展,使得以往需要花費大量時間及大量人力的藥物開發過程,減少了許多的時間及人力成本,近年來組合式化學更被應用於藥物開發的其他領域,因此了解組合式化學,是現在學化學的人,不能不做的功課。
而以carbolin為主體的化合物,不論是存在於自然界中的,或者被合成出來的,都被發現並證明具有藥物的性質。在本篇論文裡,我們用了一個新的方法來合成Tetrahydro-β-carbolinone的化合物,並可藉著改變其氮原子上的取代基,來合成一系列的衍生物。
而第二部分則是簡略的介紹了關於液晶的發展,及液晶分子的形成、分類和它的應用。
我們並以Triazole這個五環為主體,合成了一個新的桿狀液晶,且利用NMR、元素分析來鑑定分的的結構及純度,最後再用DSC及偏光顯微鏡來探討它的液晶相的溫度範圍、相的變化及紋理圖。 | zh_TW |
dc.description.abstract | ABSTRACT
Natural and synthetic products having the carboline structure often exhibit important medicinal properties. In the thesis, we synthesize the Tetrahydro
-β-carbolinone derivatives by a new method. And we can change it’s alkyl group
which is on the N atoms of Tetrahydro-β-carbolinone.
The part two in the thesis describes the synthesis of a new rodlike liquid
crystal which is triazole-based. These compounds were characterized by 1H- and 13C-NMR spectroscopy and elemental analysis. The mesomorphic properties of these compounds was characterized and studied by different scanning calorimetry(DSC) and polarized optical microscope. | en_US |
