Description
Summary:碩士 === 國立臺灣大學 === 化學研究所 === 94 === 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.
