| 摘 要： | Photochromism is a phenomenon that a compound undergoes a reversible color change with the change of the wavelength of the irradiating light. Many photochromic compounds have been used in textiles as photochromic pigments.In this paper, some special techniques are used to prepare a photochromic compound of spirooxazines with an improved yield. Another photochromic spirooxazine with a sulfonate group which is soluble in water is also successfully synthesized. Tests are also conducted to find that they both display good photochromism in proper states.
