Abstract A nonmacrocyclic azobenzene‐based photochromic receptor in its E isomer forms an extended polymeric assembly with Al 3+ ions. Exposure of the E form to UV light at λ =366 nm causes a disassembly of the polymeric structure due to the change in the molecular geometry of the ligand. The linear polymeric structure was regenerated on exposure to visible light.
