Investigation of complexation of functionalized 1,3-benzoxazinone spiropyrans with metal ions
摘要:
For the first time, complexation between the metal ions and the molecules of photochromic benzooxazine spiropyrans was found and studied. The observed spectral-kinetic changes are explained by the complex formation between molecules of the merocyanine type, resulted from the dissociation of -C-O- bonds, and by electrostatic interaction between complex components depending on the compound structure and the metal ion nature.
