High Conductivity in Molecularly p‐Doped Diketopyrrolopyrrole‐Based Polymer: The Impact of a High Dopant Strength and Good Structural Order

[3]-Radialene-based dopant CN6-CP studied herein, with its reduction potential of +0.8 versus Fc/Fc+ and the lowest unoccupied molecular orbital level of −5.87 eV, is the strongest molecular p-dopant reported in the open literature, so far. The efficient p-doping of the donor–acceptor dithienyl-diketopyrrolopyrrole-based copolymer having the highest unoccupied molecular orbital level of −5.49 eV is achieved. The doped films exhibit electrical conductivities up to 70 S cm−1. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
