Disclosed herein is a facile process for the formation of conjugated polymers inside or outside assembled solid-state devices. One process generally involves applying a voltage to a device comprising at least two electrodes, a combination of an electrolyte composition and a electroactive monomer disposed between the electrodes, and a potential source in electrical connection with the at least two electrodes; wherein the applying voltage polymerizes the electroactive monomer into a conjugated polymer. Also disclosed are electrochromic articles prepared from the process and solid-state devices comprising a composite of an electrolyte composition and a conjugated polymer.
