Patent ID: 8653291

Claim:
A process for functionalizing a surface of a substrate made of a semiconducting material, the process comprising: a) reacting a reactive group F1 of a compound of formula I: A-(E1) n1 -F1 Formula I, with a reactive group of F2 of a molecule of formula II: F2-(E2) n2 -X Formula II, and b) reacting a triple bond of the compound of formula I with a semiconducting material, wherein A is selected from: 1) an alkyne of formula: ,wherein R 1 , R 2 , and R 3 are each independently a hydrogen atom; a halogen atom; an —OH group; an —NH 2 group; an —SH group; a saturated, linear or branched, C 1 to C 30 alkyl chain which optionally comprises at least one selected from the group consisting of a heteroatom, an aryl group, an amine group, an ester group, a hydroxylamine group, an oxime group, and an amide group; and is optionally substituted by at least one halogen atom; and 2) an 8- to 12-membered cycloalkyne or heterocycloalkyne which is optionally substituted by the R 1 group, E1 is a saturated or unsaturated, linear or branched, C 1 to C 30 alkyl chain which optionally comprises at least one selected from the group consisting of a heteroatom, an aryl group, an amine group, an ester group, a hydroxylamine group, an oxime group, and an amide group, or is optionally substituted by at least one halogen atom, n1 is 0 or 1, F2 is a reactive group reacting with the reactive group F1, wherein E2 is a saturated or unsaturated, linear or branched, C 1 to C 30 alkyl chain which optionally comprises at least one selected from the group consisting of a heteroatom, an aryl group, an amine group, an ester group, a hydroxylamine group, an oxime group, and an amide group, or is optionally substituted by at least one halogen atom, n2 is 0 or 1, and X is selected from the group consisting of a porphyrin molecule, an anthracene molecule, a naphthalene molecule, a fullerene molecule, a polyoxometalate molecule, and a ferrocene group.
