In this work, we report the covalent attachment of a chiral molecule onto a hydrogen-terminated Si(SiH) surface by using an extre-mely mild approach. Cinchonine, a chiral alkaloid was self-assembled onto a SiH surface via a photochemistry method at room tem-perature. The self-assembled monolayers (SAMs) obtained were characterized by means of ellipsometry, XPS and wettability studies.The lm formation kinetics was monitored by ellipsometry and XPS, which indicated that a full monolayer was formed within 15 h.
