A homogeneous ruthenium–carbene complex was tagged with a light‐responding nitrobenzospiropyran group to control its solubility through reversible conversion between its neutral (lipophilic) and ionic (lipophobic) states using light irradiation (see scheme; Mes=mesityl). This tagged complex has significant catalytic activity in ring‐closing metathesis reactions and was recycled several times.
