Abstract:
1. A method for preparing an array of polymers comprising: providing a solid substrate comprising a reactive group protected by an acid labile protective group; coating the solid substrate with a film, the film comprising an photo acid generator and an acid scavenger; activating the photo acid generator in selected regions of the substrate by selective application of light having a predetermined wavelength to provide an acid, wherein the reactive group having the protective group is to contacted to the acid in the presence of the scavenger such that the protective group is removed to provide an exposed reactive group, wherein a step of baking is not performed following activation of the photoacid generator; contacting the exposed reactive group with a monomer, wherein the monomer is coupled to the exposed reactive group; and repeating the steps of coating; activating, and contacting the exposed reactive group with a monomer to produce the array of polymers.
