Abstract
Embodiments of the invention are directed to a method of forming a film of an insoluble conjugated polymer (CP) by deposition of an ionic CP from aqueous solution and converting the ionic CP to the insoluble CP. The ionic CP can be the salt of a carboxylic acid, sulfonic acid, phosphonic acid, boronic acid, amine, imine, phosphine, thioether, or complexed bidentate or polydentate ligand. The insoluble CP film can be used with an aqueous electrolyte solution for use as: an electrochromic film; charge injection layer for a solar cell, LED, and FET; conventional paints; supercapacitor; battery; electronic paper; anti-static coating; transparent conductor; sensors; anti-microbial coating; adhesive; RFID; or memory system.
