The role of alkyl substituents in deazaadenine-based diarylethene photoswitches

Beilstein Journal of Organic Chemistry, 2016
Diarylethenes are an important class of reversible photoswitches and often claimed to require two alkyl substituents at the carbon atoms between which the bond is formed or broken in the electrocyclic rearrangement.
