项目摘要

This study has been carried out to establish "self-organized fullerene chemistry" based on the design and syntheses of fullerene-lipidit hybrid and fullerene-lipid composite materials. The obtained results are summarized below.1. A water-soluble C_<60>-carrying single-chain ammonium amphiphile, 10-(N-Methyl-2-fulleropyrrolidyl) decyltrimethylammonium bromide (1) was synthesized. Compound 1 produces both fibrous aggregates and disk-like aggregates with 10-12 run of thickness through self-organization of 1 in aqueous solution. X-ray diffraction study suggests that cast films of 1 form a multi-layer structure. Electrochemistry for an aqueous solution and for cast films of 1 solely and 1 incorporated in lipid films on electrodes revealed that films of 1 solely and of 1/lipid cast on electrodes showed electron transfer reactions leading to the generation of the fullerene dianion or trianion. The study opens possibilities for the construction of electroactive fullerene-nanoarchitectures with … More ordered structure based on self-assembled molecular organization.2. The higher fullerene C_<84> embedded in cast films of molecular-bilayer-forming cationic lipids on electrodes was found to exhibit evident electron transfer reactions leading to the generation of C_<84> multi-charged anions. This result has both fundamental and applied implications in the chemistry and physics of fulerenes.3. The Unique properties of C_<60>-bearing artificial lipids with a triple-alkyl chain of C_<16> , C_<14>, or C_<12> were characterized by a variety of techniques including ^<13>C NMR, UV-vids and FT-IR spectroscopies, differential scanning calorimetry (DSQ, X-ray diffraction, and electrochemistry. The phase transitions of the lipid films were presented. Regulated electrochemistry at the fullerene lipid-modified electrode devices was possible. The electrogenerated radical monoanions and dianions of the fullerene lipids were found to bind strongly with "soft" electrolyte cations with large size tetra-n-butylammonium and tetra-n-butylphosphonium ions, the present study guides us toward construction of fullerene lipid bilayer devices which might be useful in the field of nanoscience and nanotechnology of fullerenes.

本研究旨在通过富勒烯-富勒烯杂化材料和富勒烯-脂质复合材料的设计与合成，建立“自组织富勒烯化学”。所得结果总结如下。1.合成了一种水溶性的<60>含碳单链铵两亲物10-（N-甲基-2-富勒烯吡咯烷基）癸基三甲基溴化铵（1）。化合物1通过在水溶液中的自组织产生纤维状聚集体和厚度为10-12 nm的盘状聚集体。X射线衍射研究表明，1的流延膜形成多层结构。电化学的水溶液和流延膜1单独和1纳入脂质膜电极上显示，1单独和1/脂质浇铸在电极上的膜显示电子转移反应，导致产生的富勒烯二价阴离子或三价阴离子。该研究为构建电活性富勒烯纳米结构提供了可能性， ...更多信息基于自组装分子组织的有序结构.发现高富勒烯C_2<84>嵌入形成分子双层的阳离子脂质膜中，在电极上发生明显的电子转移反应，导致C_2<84>多电荷阴离子的产生。这一结果在富勒烯的化学和物理研究中具有重要的理论意义和应用价值.用<60><16><14><12>~ <13>1HNMR、UV-vids、FT-IR、差示扫描量热法（DSQ）、X-射线衍射和电化学等技术表征了含有C_、C_或C_的三烷基链的含C_的人工脂质的独特性质。介绍了脂质膜的相变过程。在富勒烯脂质修饰的电极装置上调节电化学是可能的。富勒烯脂质的电生成自由基的单阴离子和双阴离子被发现与具有大尺寸的四正丁基铵和四正丁基鏻离子的“软”电解质阳离子强烈结合，本研究指导我们构建富勒烯脂质双层器件，这可能在富勒烯的纳米科学和纳米技术领域是有用的。少
