title: Photoisomerization locking of azobenzene by formation of a self-assembled macrocycle.
abstract: Reaction of an azobenzene-linked biscatecholate ligand with boron and titanium sources gave ring- and cage-shaped complexes in a self-assembly fashion, respectively. These complexes were inert to photoisomerization though the ligand itself was isomerized upon photoirradiation. The self-assembled macrocyclization caused inhibition of the photoisomerization.
