项目摘要

Recently we found that the molecular mixture of simple oxygen substituted TTF derivatives and fatty acid spontaneously forms a conducting Langmuir film on the water surface. Such reaction is very useful for obtaining conducting Langmuir-Blodgett(LB) films with its simple and easy preparation aspect. The aim of this project is development of this method and establishing it as a tool for the upcoming research field of molecular electronics. During the period of project, we carried out several studies and obtained useful knowledge as being summarized in the followings ;1.Exploring new molecular combinationsThere is a possibility to prepare novel conducting LB films with new molecular combinations through the above reaction. We examined the newly synthesized TTF molecules, EDO-TTF-SC_<18> and BEDO-TSeF, to make the combination with acetic acid(AcA) and stearic acid(SA). For both EDO-TTF-SC_<18>/AcA and BEDO-TSeF/SA, the above reaction proceeded to provide conducting LB films. The results indicate that the chemical reaction proceeds in the wide variety of molecular system of oxygen substituted TTF derivatives and fatty acid.2.The reaction with carboxyl-terminated self assembled monolayer(SAM)The reaction between BEDO-TTF and carboxyl-terminated SAM was examined for obtaining electrical conducting SAM. It was found that BEDO-TTF reacted with carboxyl-terminated SAM forming a layer of its thickness 9Å, but the film was not homogeneous and contained a lot of islands. These researches were carried out as join research project with a research group of Dr.D.Villaume (IEMN-CNRS, Lille, France).3.Application for biosensorIt is known that organic conducting material can be used as a mediator for electron transferring in amperometric enzyme sensors. As the first step for this application, we examined the immobilization of glucose oxidase in the BEDO-TTF/SA LB films. The results indicate that a certain amount of glucose oxidase can be absorbed in the LB films.

最近，我们发现简单氧的TTF衍生物和脂肪酸赞助的分子混合物形成了水面上的Langmuir膜。这种反应对于获得具有简单简便的准备方面的Langmuir-Blodgett（LB）膜非常有用。该项目的目的是开发这种方法，并将其确立为即将到来的分子电子研究领域的工具。在项目期间，我们进行了几项研究，并获得了有用的知识，因为在以下内容中总结了； 1.探索新的分子组合，可以通过上述反应准备新的分子组合的新型LB膜。我们检查了新合成的TTF分子EDO-TTF-SC_ <18>和Bedo-TSEF，以与乙酸（ACA）和硬脂酸（SA）结合使用。对于EDO-TTF-SC_ <18>/aca和bedo-tsef/sa，上述反应都进行了指导膜。结果表明，化学反应在氧取代的TTF衍生物和脂肪酸的各种分子系统中进行。2。与羧基终止的自组装单层（SAM）的反应，检查了Bedo-TTF和羧基末端的SAM之间的反应，以获得电气导电SAM。发现Bedo-TTF与羧基终止的SAM反应，形成了其厚度为9Å的一层，但是该膜不是同质的，并且包含许多岛屿。这些研究是在与研究小组加入研究小组（法国里尔的IEMN-CNRS）的研究小组中进行的。3。生物传感器的应用已知有机导电材料可以用作安培酶传感器中电子传递的介体。作为该应用的第一步，我们检查了葡萄糖氧化酶在Bedo-TTF/SA LB膜中的固定化。结果表明，一定量的葡萄糖氧化酶可以在LB膜中吸收。
