N2 - The reversible photoinduced cis–trans isomerization of the azobenzene unit in 1, together with the distinctly different association constants of the cis and trans isomers for the binding of 1 to eosin Y (2, K = 38 000 and 3000 M−1 1, respectively) can be utilized to construct a molecular switch for the formation and dissociation of the complex between 1 and 2 that is light‐controlled. Such photo‐switchable units are important in information storage systems and signal processing on the molecular level. (Figure Presented.)
