synthesis of a structurally newtype of conjugated macrocyclic ligand (1) is reported that comprises a dehydroannulene framework incorporating two 2,2'-bipyridine units. Modeling studies showed the ligand to possess an unusual chirally twisted and relatively rigid architecture capable of binding metal ions in an enforced tetrahedral coordination geometry. The macrocycle was prepared in seven steps
