| dc.description.abstract | 雙炔基衍生物具有照光聚合特性，我們於實驗中利用雙炔基衍生物(9,11-tetracosadiynoic acid 、10,12-pentacosadiynoic acid、11,13-hexacosadiynoic acid...等)溶於有機溶劑中，並將矽晶片以特定角度浸泡於溶液中，利用溶液由矽晶片退去表面同時溶劑揮發的方向性外力，將雙炔基衍生物製作成有方向性薄膜於矽晶片上，照光聚合而獲得一方向性共軛鏈，並應用於製備有機場效電晶體。另一部份我們也分析該液相成膜系統中，影響有機分子成膜性的因素如濃度、溶劑、蒸氣壓、官能基…等。結果顯示以乙酸乙酯為溶劑，在適當拉出速度下，能得到最具方向性之均勻薄膜。
將聚雙炔基衍生物薄膜利用於有機場效電晶體的半導體層，我們獲得共軛鏈與非共軛鏈電性差異，在載子遷移率(mobility)的部分共軛鏈約等於0.0586 cm2/Vs而非共軛鏈則約為0.0225 cm2/Vs，以此驗證共軛方向所影響的電性效益。

| dc.description.abstract | Diacetylenic derivatives show the characteristics of topochemical polymerization upon UV-irradiation . In this work, the diacetylenic derivatives(9,11-tetracosadiynoic acid 、10,12-pentacosadiynoic acid、11,13-hexacosadiynoic acid...) were dissolved in different organic solvents ,with a silicon wafer withdraw from the solution at a specific angle ,to prepare oriented polydiacetylene films , paraments such as , concentration、solvent type、solvent vapor pressure、functional group on the film-forming process were analysed . The results show that with ethyl acetate as solvent , smooth and oriented films can be obtained by adjusting the withdrawing speed .
Oriented polydiacetylene films were used as the semiconductor channel in field effect transistors ,and anisotropic electrical properties were measured along the conjugation direction versus other directions , with a mobility about 0.0586 cm2/Vs along the conjugation direction and 0.0225 cm2/Vs along direction perpendicular to the conjugation .
