It is shown that supercritical fluid (SCF) impregnation of polymers containing polar diphenilol and halogen groups (polyoxycarbonate, polytetrafluoroethylene, polyvinylchloride) by spirocompounds leads to conformational changes with the stabilization of merocianine form of photochroms. It is demonstrated also that previously observed effect of the formation of long-living form B of spiroantrooxazine molecules immobilized in polycarbonate matrix is also typical for other similar systems. In this work such effect is observed for a number of spirocompounds incorporated into polar polymer matrixes using the SCF impregnation method. Colored forms of spirocompounds immobilized in halogen-containing matrixes have an intense fluorescence.
