Beside its classical double strand structure formed by

• in a propeller fashion. Other recent examples are the triple-stranded phenylene cages presenting a helical rod-like shape synthesized by Kirsche et al. [10]. Hemicryptophanes are chiral covalent cages combining a cyclotriveratrylene (CTV, north part) unit with another C3 symmetrical moiety (south
