英文摘要	提出了一种简便通用的合成巯基化合物的途径，以分子中的羧基CO2H为起始基团，与2-流基乙胺的氨基选择性缩合；合成了一系列具有RC（O）NHCH2CH2SH（R分别为偶氯苯衍生物，双炔衍生物及直链烷基）结构的化合物，并用接触角测量，电化学和掠角反射红外光谱（GIR-IR）等手段对这些化合物在金表面形成的自组装单分子膜进行了表征。发现4-（N－（2‘-巯基已基））酰胺偶氮苯的自组装膜表现出良好的电活性，电化学测定表面浓度为4．21×10(－10)mol·cm(-2)．当R为烷基链时，随烷基链的增长，膜的致密度与有序度增加GIR-IR证明在自组装腹中CH3（CH2）6C（O）NHCH2CH2SH的C...; A simple and general method fro synthesizing functionalized alkanethiols is reported. The synthesis started from carboxylic acid, RCOOH, which was selectively condensed with the amino group of 2-aminoethanethiol, thus giving the targetting thiol compounds. A series of thiol compounds having a structure of RC(O)NHCH2CH2SH, where R was azobenzene derivatives, dicetylene derivatives and n-akanes, respectively, have been synthesized using this method. The self-assembled monolayers(SAMs) of these species were characterized by wettability measurement, electrochemistry and grazing incidence reflectance infrared spectroscopy (GIR-IR). The SAM from 4-((N-(2'-mercapto-ethyl)amino)carbonyl) azobenzene showed clearcut electrochemical reactivity in aqueous solution, in which the surface coverage was evaluated to be 4.21 x 10(-10) mol.cm(-2). On the other hand, for the thiols of R being n-alkanes, the packing structures became gradually improved with increasing the alkyl chain length. For CH3(CH2)(6)C(O)NHCH2CH2SH SAM, GIR-IR data indicate that the C=O and N-H groups are parallel with the substrate surface while the whole molecular axis is perpendicular to the surface.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000207601600008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 6; 06; 515-524; 13
