英文摘要	利用轴向配位作用将 5 ,1 0 ,1 5 ,2 0 -四苯基钴 ( )卟啉 ( Co TPP)固定在 4 -巯基吡啶自组装膜表面上 ,形成 Co TPP单分子膜 .通过组装金纳米粒子的方法 ,成功地获得了膜中 Co TPP分子的喇曼光谱 .研究结果表明 ,Co TPP分子是通过钴原子与氮原子之间的配位作用与巯基吡啶分子结合的 ,且其分子平面与基底表面近似平行; Using 4-mercaptopyridine (4-MPy) self-assembled on gold substrate as coupling agents, monolayer of cobalt ( II ) -5, 10, 9 15, 20-tetrakisphenyl-porphyrin (CoTPP) was fabricated on the pyridinyl-terminated surface. Further deposition of Au nanoparticles enables the detection of CoTPP molecules in monolayer to be possible by Surface Enhanced Raman Spectroscopy. The red-shift of "structure sensitive" peaks of porphyrin ring indicates the existence of chemical interaction between CoTPP molecules and the pyridine terminals, which was believed as the coordination between the nitrogen atom of pyridine ring and the cobalt atom in CoTPP. From the orientation of 4-mercaptopyridine SAMs, it can be deduced that the CoTPP molecules are approximately parallel to Au substrate in the above structure.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000170638100024&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 3; 08; 1368-1372; 22
