Lanthanide ions act as templates for self‐assembly of ligand 1 to give the triple‐stranded helicate 2 . Treating 2 with bromine and then water gives the nonadentate tripodal receptor 3 . In the absence of Ln III ions, only 20 % of the desired receptor ( fac isomer) is obtained as a mixture with the mer isomer.
