Abstract :
Photochromic spiropyran exhibited various colors depending on solvent polarity when exposed to ultraviolet light. Spiropyran was dissolved into a suspension consisting of polar droplets and non-polar oil. Since different absorption bands appeared in the droplets and oil, this transparent suspension turned to blue by ultraviolet irradiation and then turned to pink by stopping irradiation.
