Flicking the switch : Photoirradiation has a dramatic effect on the superconducting properties of a passivated ultrathin Nb film functionalized with a photochromic self‐assembled azobenzene (AZ) monolayer (see picture). These effects can be attributed to photoisomerization‐induced changes in the amount of charge transfer between the substrate and the photochromic monolayer. The changes are accompanied by alternation of the surface dipoles.
