title: Rigid π-extended triptycenes via a hexaketone precursor.
abstract: A high-yielding synthesis of a rigid hexaketone is presented that can be transformed into π-extended D3h-symmetric triptycene derivatives with high internal molecular free volumes (IMFVs). The products show excellent photophysical properties combined with high specific surface areas.
