%X Two-dimensional (2D) conducting polymers are expected to offer emergent topological, structural, and physical properties, which has become the ¡°holy grail¡± for the development of plastic electronics. Here, we report the assembly of a free-floating metallic polymer layer, consisting of poly(3,4-ethylenedioxythiophene) complexed with poly(styrenesulfonate) anions, directed by electrostatic recognition, amphiphilicity, and aromatic interactions. The obtained large-area crystalline nanosheets exhibit excellent environmental stability and mechanical robustness, meanwhile showing an electrical conductivity of 1216 S¡¤cm¨C1, the highest among the nanometer-thick conducting polymers. The kirigami-inspired freestanding polymer thermoelectrics, repeatedly stretching up to 200% strain, is demonstrated with high Seebeck coefficient with an optimized power factor of 95 ¦ÌW m¨C1 K¨C2. The large-scale assembly and aqueous compatibility of 2D conducting polymers provide an exciting platform for integrating thermoelectricity into free-floating polymer nanostructures
