Abstract

original image

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 CH[BOND]N hydrogen bonding and S[BOND]N and CH[BOND]π interactions (see picture).
