Ready for action : An excellent quantum yield was observed for a photocoloration reaction of a photochromic molecule based on a triangular terarylene structure. The molecule is brought into a conformation favorable for photocyclization by multiple intramolecular interactions, including CHN hydrogen bonding and SN and CHπ interactions (see picture).
