Coumarin spiropyrans with terminal carbohydrazide substituents were synthesized. UV irradiation of their solutions was found to initiate rearrangement into a deeply colored merocyanine form. In the presence of lanthanide cations, the obtained spiropyrans exhibited a “naked eye” chromogenic effect, accompanied by a change of the solution color from yellow to violet.
