A novel route to efficient inorganic oxide surface modifications: molecularly self-assembled linear and conjugated alkynyl thin film materials

Abstract

Treatment of surface hydroxy groups on glass, quartz and single crystal silicon with commercially available group 14 chlorides, ECl₄(E = Si, Sn), and then NEt₂H yields surface-anchored NEt₂ moieties, which react with several organic molecules containing terminal acidic protons, including rigid-rod alkynes, via acid–base hydrolysis, leading to molecularly self-assembled chromophoric monolayers.
