Matrix isolation of photochromic spiroanthrooxazine (SAO) molecules in the films of halogen-containing polymers (polyvinylchloride (PVC) and tetrafluoroethylene-vinylidene-difluoride (TVD copolymer)) performed using a supercritical fluid impregnation leads to the stabilization of an excited (colored) B-state of SAO, which does not relax into the colorless ground A-state. Such a long-living excited state can exist in the isomeric form that is characterized by the absorption band at Xmax = 535 nm ( В₅₃₅, in the TVD matrix), as well as in the «normal» B-state (Xmax > 610 nm) with a minor contribution of В₅₃₅-form (in PVC).
