Salicylate-pillared hydrotalcites of the type of Zn-0.64Al-0.37 (OH) -2[o-HO(C-6H-4)COO]-0.37 have been successfully assembled by ion exchange of a Zn-0.64Al-0.36(OH)-2(CO-3)0.18 precursor in an organic solvent. The samples thereby obtained were characterized by XRD, FT-IR and TG-DTA. The results show that the original interlayer carbonate ions of the hydrotalcite precursor can be completely replaced by salicylate anions under controlled conditions . The interaction of the host layers and the guests , as well as the arrangement and orientation of the guests between the layers were investigated . The salicylate-pillared hydrotalcites have good thermal stability and can block UV radiation over a wider range
