摘要

本論文除緒論外，主要分為三部分：
第一部份為含氫鍵香蕉形液晶分子及氟取代基對液晶性質的研究：在此部分設計多系列之氫鍵香蕉形液晶分子加以探討，並利用變
溫紅外線光譜來判別其溫度對氫鍵強弱之變化。
第二部份為鹵素鍵對液晶分子之研究，在此亦設計多系列之鹵素
鍵化合物，希望對於鹵素鍵有更深入之瞭解。
第三為微波反應下之有機反應，包括(一)Duff反應，將對電子效
應和立障效應，觀察其結果做出結論。(二)，改良傳統之氧化反應方式，並試著回收其可再利用之部份，以達到永續化學之精神。

The present paper mainly divides into three parts:

The first part contains the hydrogen-bonded banana liquid crystals and the fluorine substituting group to the liquid crystal research: Designs the multi-series hydrogen-bonded banana liquid crystals in this part to discuss, and using temperature-controlled infrared spectrum to distinguish the changes between the hydrogen bond and molecular structure.

The second part focuses on the banana-shaped liquid molecules with halogen bond, and designs the multi-series compound with halogen bond.The more comprehensibility on halogen bond will be grasped.

The third part is about the microwave reaction, Duff reaction is also the quite interesting part, and then we focus on the electric effect and the hindered effect to disscus its result to draw the conclusion.

Finally, the present paper will be able to improve the oxidizing reaction way, and will recycle the recyclable part, achieving the spirit of green chemistry.
