Graphical Abstract
  • quickly identified the triptycenyl-based imine cages of Mastalerz [301] as a strong starting point because: (i) they offered efficient, modular assembly; (ii) all of the complexity could be confined to the privileged triptycene motifs, which would present rigid internal vectors into the cavity for
