Progress on Synthesis of Photochromic Spirooxazines

As important organic photochromic compounds,spirooxazines exhibit excellent chemical stability,photosensitivity and photofatigue resistance,and have potential applications in the fields of light filters,camouflage and optical data recording & storage.The design & synthesis of spirooxazines has been a focus in the field in order to obtain photochromic spirooxazines with the better performance.Based on the basic synthetic methods of photochromic spirooxazines compounds,the typical synthetic methods and photochromic properties of spirooxazines,including biphotochromic spirooxazines and photochromic siprooxazine polymers,are reviewed.The influence of main structure of spirooxazine on the photochromic properties is briefly discussed.The introduction of ultrasound and microwave in the synthesis of spirooxazine is presented.The important study direction in the synthesis of spirooxazines is suggested.
