Modulation of color change and photocyclization of diarylethene with metal complex is described. A diarylethene derivative with 4‐(ethylideneamino) phenol group 1a is prepared and photochromic behavior is investigated. It is found that 1a exhibits ring‐opening and ring‐closing photoisomerization with UV/Vis light irradiation in solution. Addition of Cu(OAc) 2 to the solution of 1a produces a metal complex 1a–Cu , which generates not only marked color change but also significant promotion in photocyclization.
