Overall research concept of this work (IMAGE) Waseda University Caption a) Molecular design of poly(thiourea)s (PTUs) with polarizable group synergy, b) plausible schematic representation of disordered (various conformational) H-bonding networks between the PTU chains enabling polarizable supramolecular networks, and c) schematic representation of the architecture of light-emitting electrochemical cells.
