Abstract:
A series of co-crystals of 1,1-difluorosumanene (F2-Sum) and sumanene (Sum) were obtained. The co-crystallization successfully tuned their structural and physical properties, especially the dielectric response, without any chemical modifications. X-ray analyses and theoretical calculations revealed the reduction of intermolecular interaction energy due to the presence of F2-Sum.
