Description
Summary:Tayi et at1 reported room-temperature ferroelectricity in organic mixed-stack charge-transfer crystals, produced using a supramolecular design concept-the lock-arm supramolecular ordering (LASO)-that synergistically combines intermolecular charge transfer and hydrogen bonds2,3. Here we present an independent experimental investigation that found no evidence for ferroelectricity in one of the LASO compounds described in ref. 1 and, together with theoretical calculations, demonstrates that a possible ferroelectric behaviour is not of electronic origin as proposed in ref. 1.
