Abstract: In this paper,salicylate-pillared MgAl hydrotalcite organic/inorganic hybrid was synthesized by using direct anion exchange method in the aqueous solution with NO3-MgAl as precursor,and was characterized by XRD,IR and DTA.The guest-host interaction in the synthesized sample was investigated.Results show that the thermal stabilities of the brucite-like layers and the inserted anion pillars in the salicylate pillared hydrotalcite are largely improved due to the guest-host interaction.DTA combined with the XRD and IR studies  of the sample calcined at different temperatures reveal that the grafting of the guest anions to the host brucite-like  layers takes place during the thermal processing accompanying the Hydrogen-bonding formation,and the proper grafting temperatures are between  the elimination of water molecules from the interlayer space and the elimination of the hydroxyl groups from the brucite-like layers.

Key words: hydrotalcite, organic/inorganic hybrids, synthesis, grafting
