Patent ID: 8173347

Claim:
A method for modifying a surface of a self-assembled monolayer, comprising: a) forming on a substrate a self-assembled monolayer of organic groups, wherein each organic group has the general formula W-Sp-ff, wherein W is a heteroatom or a group containing at least one heteroatom, Sp is a spacer comprising an alkylene chain in which one or more carbon atoms may be replaced with a heteroatom, a group containing one or more heteroatoms, an arylene group, or a combination thereof, and ff is a non-acidic first functionality capable of being converted to a second functionality by exposure to an acid; b) forming a coating on the self-assembled monolayer, wherein the coating comprises a photoacid generator; and c) selectively photoirradiating the coating to generate an acid in each irradiated region of the coating, wherein the acid converts the first functionality of the self assembled monolayer underlying the respective irradiated region of the coating to the second functionality.
