Sythesis and photochromic properties of 9′-furanacryloxyspirooxazines;

Confirmation of Structure for Novel Organic Photochromic Compounds Spirooxazine;

Synthesis of a novel photochromic spirooxazine compound;

Spirooxazines (SOs) and spiropyrans (SPs) are typical organic compounds exhibitingphotochromism.

Among the vast number of reports on the photochrometry of spirooxazine derivatives in the literature, researchers are mainly interested in two aspects: one designs different spirooxazines, and looks into the influence of the structure on the photochromic behaviour; the other inquires into the (influence) of the medium on photochromic behaviour.

Photo-induced birefringence of spirooxazine-doped PMMA films is alternately pumped by s and p polarized He-Ne beams (632.
