通过在稀有气相C-C键形成反应中添加双(三氟甲基)亚甲基基团以直接产生携带末端CF 3基团的膜,对氧化硅衬底上的乙烯基封端的自组装单分子膜(SAMs)进行化学改性。用六氟丙酮吖嗪(HFAA)对乙烯基封端的薄膜进行改性。薄膜的特征在于椭圆偏振仪,接触角测量,原子力显微镜(AFM),和X射线光电子能谱(XPS)。在这项研究中,我们发现,对于优化的条件下,清洁的反应发生在表面之间的自组装膜与末端烯烃和HFAA,和产品是一致的双(三氟甲基)环丙烷化形成后,氮气挤出。
Vinyl-terminated self-assembled monolayers (SAMs) on silicon oxide substrates were chemically modified by the addition of a bis(trifluoromethyl)methylene group in a rare gas-phase C–C bond-forming reaction to directly generate films carrying terminal CF3 groups. The vinyl-terminated films were treated with hexafluoroacetone azine (HFAA) for modification. The films were characterized with ellipsometry, contact angle measurements, atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). In this study, we find that for optimized conditions clean reactions occur on a surface between SAMs with terminal olefins and HFAA, and the product is consistent with bis(trifluoromethyl)cyclopropanation formation after nitrogen extrusion.
