摘要

1.本實驗是利用4,4'-Biphenol為起始物，與Allyl bromide反應，產生丙烯基芳基醚化合物，再利用克萊森重排反應( Claisen rearrangment )將丙烯基轉至鄰位，然後在將OH基轉變為不同鏈長的烷基醚合成出聚合物（A）∼（I），以FT-IR、NMR-1H、UV、PL測定其發光性質及判斷產物結構是否正確，並探討化合物在不同側鏈之條件下，比較其放射波長。實驗結果顯示，由Isolate轉至Conjugates過程中，環外雙鍵因碳碳雙鍵與苯環共軛作用，使其分子較為穩定，導致螢光光譜(PL)最大放射波長往紅位移方向移動，而在光譜TGA上，其5%熱重損失溫度也隨之提高。
以TGA、DSC測定其熱性質，並了解到由TGA的5%熱重損失溫度再進行測出液晶溫度範圍，我們成功的合成出具有良好的加工性的共軛性分子，發光性質都出現在藍光領域，願在有機發光二極體的領域上有重大的貢獻。

2.利用現有的高分子聚合材織造的布料為反應原料，並利用微包化後的乳化聚合高分子，以浸染的方式，塗佈在反應布料上，所使用的乳化聚合高分子含有氫原子及氟原子的長鏈碳作為疏水性長鏈官能基，乳化聚合後的高分子或共聚合高分子，含有可與現有的高分子布料或天然棉反應的官能基，如在乳化聚合後的高分子或共聚合高分子上留有氫氧基、胺基或酸基等，再利用這些官能基與天然棉或尼龍上的官能基作用，形成鍵結，使疏水性高分子分佈於天然棉或尼龍織布上，乳化聚合高分子將控制粒徑在0.5um以下，且產率均高達95%以上。

1.In this study, main chain of 4,4'-Biphenol combine different side chains to discuss polymer(A) ~ polymer(I) which synthesizes by the difference of structure of 1-Bromobutane、1-Bromoocatane、1-Bromododecane.To examinate luminance property and judge the correction for the structure of polymer(A) ~ polymer(I) by FT-IR、NMR-1H、UV、PL, in the meanwhile,to investigate into radiation wavelength under the condition of different side chains. The results showed that it is do stable since the resonance of external carbon double bond and benzene from isolate to conjugate that PL maximum wavelength bring to red shift, and it demands higher energy to break up intermolecular effort .
To examinate the thermal properties by TGA、DSC and figure out the maximum decompose temperature which survey the range of liquid crystal temperature. We synthesize conjugated polymer successfully and these emitted blue fluorescence. Hope this experiments will supply well-contribution in field of organic light-emitting diodes.

2.Copolymers that contain hydrophobic groups, such as fluorinated alkyl group, were used to bond covalently with nylon 66 fabrics and cotton fabrics. The bond is made with the copolymer’s active functional site. Such copolymers were produced from micelles to control their mean molecular weight and dimensions below 0.5μm. The modified nylon 66 fabrics and cotton fabrics were characterized by scanning electron microscopy (SEM) and by determining the contact angle. The grafting percentage of all of the substrates did not exceed 30%, and the contact angles exceed 100 degree. Finally, we successful control dimensions below 500nm and conversion exceed 95％。
