The present invention provides a process for producing an electroactive substrate. The process includes providing a substrate having an oxidant layer on a surface thereof, exposing the surface containing the oxidant layer to a vapour containing an aryl or heteroaryl monomer that is polymerizable to form an electroactive polymer, and polymerizing the aryl or heteroaryl monomer in the presence of a volatile Lewis base to form a polyaryl or polyheteroaryl electroactive polymer film on the surface of the substrate. The invention also provides electroactive substrates formed by the process.
