Abstract

Disclosed herein is an article comprising a substrate; a first region having a first brush polymer chemically bonded to the substrate; where the first brush polymer comprises repeat units of a first ethylenically unsaturated monomer and a second ethylenically unsaturated monomer; where the first ethylenically unsaturated monomer comprises a first electroactive moiety and where the second ethylenically unsaturated monomer comprises a second electroactive moiety that is different from the first electroactive moiety; where at least one of the first electroactive moiety or the second electroactive moiety is an emitter moiety and where the repeat units of the first ethylenically unsaturated monomer are covalently bonded to repeat units of the second ethylenically unsaturated monomer.
