Abstract:

The paper describes a systematic study on the synthesis of Zn-Al layered double hydroxides (LDHs). Different guest species intercalated LDHs have been synthesized by the methods of coprecipitation and ion exchange, respectively, such as o-, m-, p-nitrobenzoic acid. PXRD, FTIR, UV/Vis and theoretical calculation were used to study the photosensitivity, and the possible mechanism was proposed, which provides a theoretical basis and a prerequisite for the application of the new photosensitive materials.

Key words: layered double hydroxides, photochromism, supramolecular structure, intercalation
