Azobenzene derivatives are excellent candidates for optical switching systems, due to their facile and reversible photoisomerization. However, the chromophores are usually aggregated in Langmuir–Blodgett films, which suppresses this cis–trans isomerization. Here is reported the anchoring of palmitoyl and azobenzene functions to a fifth‐generation dendrimer (see Figure) to yield very stable monolayers that show reversible photoinduced switching.
