摘要： 首次制备了三氯锗丙酸及其酯类衍生物(Cl3GeCH2CH2COOCnH2n+1,n=0,2,4,6)在羟基化的单晶硅片上的自组装单分子膜,并利用接触角测量、椭圆偏振和光电子能谱法进行结构表征.结果表明,这类分子的自组装行为与三氯硅烷相似,组装后在基底表面形成准二维锗烷网状排布;分子链轴有一定倾斜角;膜表面润湿性随表征液体和三氯锗丙酸尾链取代基不同而不同.

Abstract: Self-assembled monolayers(SAMs) of trichlorogermanyl propanoic acid derivatives on hydroxylated silicon subst rates are prepared for The first time.Contac TANGle measurement, ellip-sometry and X-ray photoelectron spectrometry(XPS)are used to characterize these SAMs.It is demonst rated that a quasi 2-D network is formed on the surface of the substrate after molecules ad-sorbed on it.The molecular chains have certain til TANGles to The subst rate surface.The wettabili-ties of The SAMs are various, because The molecules adsorbed and liquids used in The experiment sare different.It can be concluded that trichlorogermanes have similar self-assembly behavior as trichlorosilanes.Four SAMs are st udied togeTher:They are acid, ethyl, butyl and hexyl surfaces whose results are of good consistency.

Key words: Trichlorogermanyl propanoic acid, Self-assembled monolayers, Wettability
