A New Azaferrocenophane with an Azobenzene-Containing Ligand. Remote Control of Photoisomerization of the Azobenzene Group by Redox of the Iron Center

Azobenzene-introduced azaferrocenophanes have been newly synthesized by coupling reactions catalyzed by transition-metal complexes. The photochemical response of the azobenzene group is controlled by the oxidation state of the molecule.
