Abstract
Spirooxazine (SPO) was introduced into hydrophobically modified montmorillo nite dispersed in acetone under UV illumination in the presence of zinc ion s. The fluorescence spectra of the samples exhibited photochromic behavior arising from the photoinduced interconversion between the original species of SPO and the Zn-chelated complex of the SPO-derived merocyanine.
