The design rules for creating multifunctional organic electronic materials are currently limited. By copolymerizing twisted triphenylamine (TPA) and electron rich dioxythiophene (XDOT) monomers via Direct (Hetero) Arylation Polymerization (DHAP), a set of polymers are obtained that perform as yellow to transmissive electrochromic (EC) films with up to 45% contrast, as well as in electroluminescent (EL) applications, achieving a luminance of approximate to 450 cd/m(2) in yellow-green polymer light-emitting diodes (PLEDs). In addition, polymerizing TPA with a donor-acceptor-donor monomer results in a low-bandgap polymer that achieves power conversion efficiencies up to 2.5% when blended with PC71BM in conventional organic photovoltaic (OPV) devices. Incorporation of TPA units into the polymer backbone largely breaks any aggregation and ordering in the solid-state, leading to highly soluble materials that form smooth, reproducible thin films. The TPA unit also serves to break conjugation throughout the polymer backbone, providing precise control over optical and electronic properties through choice of comonomer. These results suggest that TPA copolymers can be useful for achieving multi-functionality without sacrificing facile solution processability, making them promising candidates for multifunctional devices like dual EC/EL displays.
