Abstract:
A method of modifying a surface, the method comprising contacting the surface with a hydridosilane under conditions and for a time sufficient to form a covalent bond between the silicon atom of the hydridosilane and the oxygen atom of a hydroxyl group on the surface, wherein the hydridosilane has the formula wherein each of Ra, Rb, Rc, and Rd is, independently, H, linear or branched C1-30 alkyl, cyclic C3-30 alkyl, linear or branched C2-30 alkenyl, linear or branched C2-30 alkynyl, C6-20 aralkyl, C6-10 aryl, or a polymeric moiety having a molecular weight of about 1000 to about 100,000, wherein the polymeric moiety is selected from the group consisting of hydrocarbon polymers, polyesters, polyamides, polyethers, polyacrylates, polyurethanes, epoxies, and polymethacrylates,each of Ra, Rb, Rc, and Rd being optionally substituted with one or more substituents selected from the group consisting of â€”F, â€”Cl, â€”Br, â€”CN, â€”NO2, &boxH;O, â€”N&boxH;C&boxH;O, â€”N&boxH;C&boxH;S, â€”CH2â€”CH2â€”Oâ€”, â€”CH2â€”CH2â€”Sâ€”, â€”N3, â€”NReRf, â€”SRg, â€”ORh, â€”CO2Ri, â€”PRjRkRl, â€”P(ORm)(ORn)(ORp), â€”P(&boxH;O)(ORq)(ORs), â€”P(&boxH;O)2ORt, â€”OP(&boxH;O)2ORu, â€”S(&boxH;O)2Rv, â€”S(&boxH;O)Rw, â€”S(&boxH;O)2ORx, â€”C(&boxH;O)NRyRz, and â€”OSiRaaRbbRcc, wherein each of Re, Rf, Rg, Rh, Ri, Rj, Rk, Rl, Rm, Rn, Rp, Rq, Rs, Rt, Ru, Rv, Rw, Rx, Ry, and Rz, is, independently, H, linear or branched C1-10 alkyl, cyclic C3-8 alkyl, linear or branched C2-10 alkenyl, linear or branched C2-10 alkynyl, C6-12 aralkyl, or C6-10 aryl, and is optionally substituted with one or more substituents selected from the group consisting of â€”F, â€”Cl, and â€”Br, and wherein each of Raa, Rbb, and Rcc is, independently, linear or branched C1-10 alkyl, cyclic C3-8 alkyl, linear or branched C2-10 alkenyl, linear or branched C2-10 alkynyl, C6-12 aralkyl, C6-10 aryl, â€”F, â€”Cl, â€”Br, or ORdd, wherein Rdd is linear or branched C1-10 alkyl, provided that at least one of Ra, Rb, Rc, and Rd is H and at least one of Ra, Rb, Rc, and Rd is not H.
