Abstract
The invention includes a trialkylsilane comprising a hydrocarbon backbone including one to ten carbon atoms; a terminal trialkylsilyl moiety having at least two alkyl groups independently comprising at least six carbon atoms; and a terminal silyl moiety that has at least one hydrolyzable group bound to a silicon of the silyl moiety. At least one of the alkyl groups of the trialkylsilyl moiety may substituted with at least one halogen, and is preferably a perfluoroalkyl group. The invention also provides methods of producing the trialysilane and substrates including the trialkysilane of the invention, as well as columns and substrates for use in chromatographic applications.
