Bathed in light , the acyclic receptor 1 that binds a neutral guest molecule through hydrogen bonding ( 1 ⋅ 2 ) undergoes an intramolecular anthracene photodimerization reaction to yield a macrocyclic structure. The dramatic change in the structure of 1 from open to cyclic affects the binding properties of the receptor sites and leads to the exclusion of the guest molecule.
