Abstract:
1. A functionalized Si/Ge surface, the Si/Ge surface being selected from the group consisting of silicon nitride, silicon carbide, germanium nitride, germanium carbide and silicon germanium surfaces, wherein the Si/Ge surface is covalently bonded to moieties being represented by the general formula (1): wherein A is a linear, branched or cyclic alkylene or alkenylene group having 2 to 24 carbon atoms, the alkenylene group being a 1-alkenylene or an internal alkenylene group; B is a functional group selected from: —CH═CR —C≡C —XR —N(R —NR —O—[(C(R —C(X)XR —C(X)NR —S(O)OR —S(O) —S(O)NR —S(O) —P(O)(R —P(O)(OR —CN, —Cl, —Br, —I, —NCX, —XCN, a group of the general formula (2) and tautomers thereof: or a group of the general formula (3) and tautomers thereof: wherein R R R R R* is a group as defined for R p is an integer in the range of 2-4; q is an integer in the range of 1 to 500; X is independently O or S; n is an integer in the range of 1 to 3; and wherein the Si/Ge surface is functionalized by reacting with ω-functionalized alkene or alkyne.
