摘要
Abstract The colorless liquid spiropyran possessing long alkyl chains (SP1822) is transformed to the colored merocyanine state upon UV irradiation. Then, two different solids (J- and H-aggregates) are formed selectively depending on the temperature. These aggregates are converted independently to the initial liquid thermally and photochemically.
