title: Recyclable nitrate-templated photochemical [2+2] cycloaddition reaction promoted by a tripodal receptor.
abstract: A nitrate-templated stereoselective photochemical [2+2] solid-state synthesis that is promoted by a supramolecular encapsulation/release of the anion template is reported. The complete reaction process with the same nitrate template can be recycled in a repetitive manner.
