Abstract
Low surface energy functionalized surfaces on solid supports are provided by treating a solid support having hydrophilic moieties on its surface with a derivatizing composition containing a mixture of silanes. A first silane provides the desired reduction in surface energy, while the second silane enables functionalization with molecular moieties of interest, such as small molecules, initial monomers to be used in the solid phase synthesis of oligomers, or intact oligomers. Molecular moieties of interest may be attached through cleavable sites. Derivatizing compositions for carrying out the surface functionalization process are provided as well.
