Research Abstract

Honeycomb arrangement of molecules in a crystal or on a substrate would lead to the same electronic structure as graphene. We focused on π-conjugated molecules having three-fold symmetry and actually prepared them, and investigated their structure and physical properties. X-ray crystallographic analysis demonstrated that the compound with fluoranthene moieties gave a honeycomb structure in the crystal. We also prepared a CT complex of the compound with F4-TCNQ and X-ray crystallographic analysis revealed that the CT complex also adapts a honeycomb structure
