A related series of bisamides have been evaluated for rational correlation between anion complexation and organocatalysis: remarkable enhancement of hydrogen bonding to anions was observed along with significant increases in catalytic activity in the Baylis–Hillman reaction. In addition, X-ray crystallography showed a large degree of pre-organisation was observed in one receptor by incorporation of

Anion-templated pseudorotaxane formation is effectively controlled by macrocycles that expand and contract in response to a light stimulus. Upon light-induced threading and dethreading, the axle component can dynamically relocate between the macrocycle and a secondary isophthalamide host. This work is a stepping stone towards signal processing in multicomponent supramolecular systems.
