英文摘要	报导了酞菁氧钒(VOPc)分子及其纳米簇在高定向石墨(HOPG)表面的自组装.在室温下,将HOPG浸入含有VOPc纳米簇(2-20nm)和VOPc分子(约为10-3g·L-1)的1,2-二氯乙烷胶体溶液中,VOPc分子在HOPG表面自组装形成单分子层(SAM),VOPc纳米簇在上述SAM表面进行尺寸选择性自组装.组装于VOPc单分子层表面的纳米簇的粒径为(4.60±0.47)nm.扫描隧道显微镜研究表明,随着酞菁氧钒胶体溶液浓度由2.5×10-2g·L-1增至2.5×10-1g·L-1,组装于SAM表面的VOPc纳米粒子的数量逐渐增多,最终形成稠密的单层粒子组装体.本文提供的自组装结构及方法在...; Self-assembled monolayer (SAM) of oxovanadium phthalocyanine (VOPc), an organic semiconductor compound. was prepared at room temperature on a highly oriented pyrolytic graphite (HOPG) substrate by immersing the substrate in a 1,2-dichloroethane (C2H4Cl2) colloidal solution containing both VOPc nanoparticles (2-20 nm) and dissolved VOPc molecules (ca 10(-3) g.L-1) The VOPc nanoparticles further assembled on the VOPc SAM The nanoparticle-assembling in the experimental conditions exhibited a high size-selectivity to VOPc nanoparncles of (4.60 +/- 0.47) nm with a standard deviation of 10% As revealed by scanning tunneling microscopy (STM) measurements, with increasing VOPc concentration of the colloidal solution from 2 5 x 10(-2) to 2 5 x 10(-1) g . L-1. the amount of VOPc nanoparticles assembled on the molecular layer increased gradually, and a dense VOPc nanoparticle monolayer formed in the end The found assembly structures and method are promising for the development of photoelectric or electric functional systems; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000276958400020&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 4; 04; 933-938; 26
