A method for preparing a defunctionalized alkylenedioxyheterocycle polymer or copolymer involves providing a polycarboxylic acid derivative functionalizcd alkylenedioxyheterocycle polymer or copolymer and transforming the polymer or copolymer into a defunctionalized alkylenedioxyheterocycle polymer or copolymer which is a polyhydroxy, polythiol, polyamino, or polycarboxylic acid functionalizcd alkylenedioxyheterocycle polymer or copolymer. The monomers, homopolymers and copolymers for use in the method are new compositions of matter. The polymers containg polycarboxylic acid derivative functionalized alkylenedioxyheterocycle units are soluble polymers which are defunctionalized to yield insoluble polyhydroxy, polythiol, polyamino, or polycarboxylic acid functionalized alkylenedioxyheterocycle polymers. These polymers can be cast as films for use as: hole transport layers in organic light emitting diodes; active electrochrome in electrochromic windows, mirrors and displays; field effect transistors, supercapacitors, batteries, photovoltaic cells, and other electronic components; electronic paper; anti-stat conductors; and transparent conductors.
