Abstract
4-Phenylazobenzoyl chloride or 4-phenylazobenzoic acid was intercalated into interlayer space of kanemite containing surfactants. After extraction of the surfactants in the interlayer space with ethanol, kanemite-azobenzene composites containing physisorbed and chemisorbed species were obtained. Cis-trans photoisomerization of the azobenzene unit existing in the interlayers has been observed under UV irradiation.
