Photochromism of a Spiropyran in the Presence of a Synthetic Hectorite
The photoinduced reaction in a system consisting of a photochromic spiropyran and a synthetic hectorite in toluene was examined. The photomerocyanine formed from spiropyran was adsorbed on the hectorite from toluene solution and the desorption of the adsorbed merocyanine from the hectorite as spiropyran was induced by visible light irradiation.
