As reported by Antonio Facchetti, JunTakeya, and coworkers, molecules of an n-type semiconductor PDIF-CN2 assemble with perfect periodicity into a molecular-crystal plate. The plate, formed in a narrow gap from a solution, works as an excellent n-type semiconductor. It is implemented in the best-performing printed logic element.
