本研究希望了解薁類分子所具有雙極的特性在金表面上形成自組裝單層薄膜時的排列情形，透過二硫醇化合物與金表面形成自組裝薄膜時，二硫醇會裂解成硫醇的單體與金表面做鍵結的特性，來製備薁類分子於金表面的單層薄膜。
首先，由起始物2-對甲苯磺醯氧草酮(B)合成薁類的中間物2-氧-2-氫-環庚〔b〕呋喃-3-羧酸甲酯(C)，將化合物C與1，4－氧氮陸圜(Morpholine)、丙醛反應生成3-甲基-薁-1-羧酸甲酯(D)，化合物D與磷酸反應生成1-甲基-薁，參考Anderson的合成方式將1-甲基-薁合成為二-3-甲基-薁基亞甲基二硫化合物，並透過質譜、紅外線光譜、核磁共振光譜來鑑定化合物。
把化合物二-3-甲基-薁基亞甲基二硫化合物溶於純化後THF溶劑中，並將蒸鍍有金的基材浸入溶劑中，分別製備24小時、48小時、72小時的片子各一片，先將片子以橢圓儀計算膜厚，再測出反射式紅外線光譜，比對反射式紅外線光譜與化合物於溴化鉀的穿透式紅外線光譜，觀察分子於表面的排列情形。
橢圓儀的數據中出現了有一致性的膜厚，然而反射式紅外線光譜並沒有出現明顯的圖譜能夠做為判別分子於金表面排列結構的證據，未來希望透過高解析的STM來觀察薁類分子於金表面的排列情形，再利用NEXAFS的數據來解出分子間相對的結構關係，以提供薁類分子於金表面排列研究的基礎。

In this paper we try to understand application of the dipolar property of azulene to effect the structure of self-assembled monolayer(SA films) on the gold surfaces. Making use of the reaction of the disulfides on gold surfaces to form RS——Au+ , we try to prepare the azulenethiol monolayers on gold surfaces.
We start with p-touenesulfonyloxytropone(B) to synthesize the intermediate of azulene, methyl 2-oxo-2H-cyclohepta[b]furan-2-one(C). Intermediate C has been reacted with morpholine and propylaldehyde to accomplished methy 3-methyl-azulene-1-carboxylate(D). Compound D has been reacted with phosphoric acid to accomplish 1-methyl-azulene, and synthesize di-(3- methyl-azulyl methlenyl) disulfide from 1-methyl-azulene according to the method of Anderson and identified the compound by using mass spectrometry、infrared spectrometry and proton magnetic resonance spectrometry.
Self-assembled monolayers of di-(3- methyl-azulyl methlenyl) disulfide was prepared onto gold surface by submerging it into the THF solution of compound for 24 hours, 48 hours, and 72 hours. Using ellipsometer to measure the thickness, and compare the reflection of the adsorption IR spectra of SA films with the adsorption IR spectra of compound to explain the arrangement on gold surface.
Although our data show the consistency of the thickness no clear evidences explain the arrangement on gold surface. We hope using STM and NEXAFS to observe the arrangement on gold and the structure inter the molecule in the future and to provid the basic research for the arrangement on gold surface of azulene molecules.
