摘要

第一部分:
由N-carbobenzyloxy-L-isoleucine及其衍生物為起始物與1-aminodecane、1-aminooctadecane、1,7-diaminoheptane、1,10-diaminodecane及1,12-diaminododecane在醋酸乙酯中反應可製備N-carbobenzyloxy-L-isoleucylaminodecane及其系列之衍生物，再加入KI / acetonitrile溶液中以製備出低分子量凝膠電解質，此有機膠體電解質的離子導電率會隨濃度的增加而少許地降低，但凝膠強度卻因此而大幅增強。此系列凝膠化合物可製作全固態染料敏化奈米太陽能電池中的膠體電解質。

第二部分:
此研究主要探討如何利用噴印方式來製作微米細導線，由噴墨的過程中發現到墨滴乾燥成膜時會產生一種自然現象，一般稱為咖啡環(coffee ring)，coffee ring effect 是結合了溶解度、蒸氣壓、黏度及表面張力等多項因素所產生的自然現象，這項研究利用工程的手法企圖以田口工程實驗的方式，以瞭解各種物理及化學因子對於coffee ring形成趨勢之預測，由實驗結果中找出適合噴印製作微米細導線的參數，而PMMA與PVA為實驗主要探討的關鍵材料，可用來作為有機薄膜電晶體(OTFT)中的絕緣層，由實驗結果找出最佳參數值可製作出2~5µm的細導線，未來對於應用於OTFT元件的製作有相當的助益。

Part I

N-carbobenzyloxy-L-isoleucylaminodecane and the other derivatives, was prepared from N-carbobenzyloxy-L-isoleucine and 1-aminodecane, 1-aminooctadecane, 1,7-diami-nohe-ptane, 1,10-diaminodecane, 1,12-diaminododecane using N,N’-dicyclohexylcarbo-diimide (DCC) as the coupling reagent. Using N-carbobenzyloxy-L-isoleucylaminodecane as a low molecular weight gelator for polar solvents, organogel electrolytes were prepared from supporting electrolyte and a polar solvent such as acetonitrile, Dimethylsufloxide, and Dimethyl Formamide by physical gelation. The ionic conductivity of the prepared organogel electrolytes decreased very slightly with increasing concentration of gelator, while the gel strength drastically increased with increasing concentration. This type of gelator can be applied to organpgel electrolytes fabrication of dye-sensitized solar cells.

Part Ⅱ

This study is to discuss how to produce the organic micro-wire by ink-jet printing. The drop drying will produced nonunifrom film, attributed to coffee ring effect. Coffee ring effect is natural phenomena caused by many factors, such as the concentration, viscosity and surface tension of the solution and the vapor pressure of used solvents. We try to understand many physical and chemical factors correlated to the trend of coffee ring forming by using Taguchi method. We find out the suitable parameter of producing the organic micro-wire from the experimental results. PMMA and PVA are the main material used in this research, since it can be used as insulator in Organic Thin-Film Transistor (OTFT). The width of the narrow wire can reach about 2~5µm with proper parameters obtained from the system analysis. In the future, these results can be applied to the short-channel OTFT fabrication.
