Synthesis, photochromic properties, and complex formation with metal ions of hydrazones based on a spiropyran of oxaindane series

A series of hydrazones based on a new spiropyran oxaindane series was synthesized. The compounds were found to possess photochromism and are characterized by a high rate of spontaneous decoloration of their photoinduced merocyanine form. Dark and photoinduced formation of complex compounds in the reaction of metal ions with molecules of the hydrazones in solution was observed.
