ABSTRACT
The halogen bonding and the p···p stacking interactions induce the noncovalent self-assembly of modules into photoreactive supramolecular architecture. The p···p interaction pre-organizes the template, and the halogen bonding aligns the olefins to conform to the topochemical principle for photoreaction. The UV irradiation of the crystal resulted in a cyclization product with quantitative yield and stereospecificity.
