pseudorotaxane assemblies between a designed macrocyclic halogenbonding (XB) acceptor (red in scheme) and a series of XB donor threading components was templated by a singlehalogenbond. The strength of the XB assembly between the pyridine macrocycle and iodopyridinium thread was utilized in the ring‐closing metathesis clipping synthesis of a [2]catenane.

The anion‐templated synthesis of a halogen‐bonding catenane, which recognizes chloride and bromide ions solely by halogen bonding, is described. The catenane's ability to optically sense halide anions using fluorescence spectroscopy is demonstrated.
