Photochromism of diarylethene intercalated in clay interlayers

The synthesis and photochromism of clay-diarylethene (PyDE) hybrid material s have been investigated. The obtained hybrid materials efficiently exhibit ed photochromism, but its photochromic efficiency decreased when UV and vis ible irradiation was repeated. This photochromic degradation could be impro ved by coadsorbing the cationic surfactant molecules with the PyDE molecule s.
