A supramolecular protecting group strategy has been applied to achieve solid‐state photodimerizations of olefins lined with a combination of hydrogen‐bond‐donor and ‐acceptor groups. Esters were used as protecting groups to generate head‐to‐head photodimers that were readily converted into diacids. A protected olefin equipped with a stilbene unit exhibits enhanced reactivity that is ascribed to pedal
