The synthesis of a light‐responsive N‐heterocycliccarbenecopper(I) complex by introducing a nitrobenzospiropyran unit into the carbene ligand was developed. The solubility of this complex was controlled through reversible conversion between its netural and ionic states using ultraviolet light irradiation. Taking advantage of such a light‐sensitive property facilitated its recovery and reuse in copper(I)‐catalyzed
