ABSTRACTIncorporation and subsequent stabilization of organic molecules into layered double hydroxide are investigated. Through two types of hybrid materials, organic dyes and aniline-based monomers interleaved between LDH materials of cation composition Zn2Al and Cu2Cr respectively, it is shown that the effect of the constrainment is revealed by the interactions different according to the molecule size and stacking as exemplified by dye molecules, orange 6 and green 25 acids and two aniline-based monomers, m-amino-4-benzenesulfonic and 3-aniline-1-propanesulfonic acids.

AbstractLayered double hydroxides (LDHs) are known as ‘anionic clays’. They comprise a class of material with positively charged octahedral double hydroxyl layers and exchangeable anions. The Li/Al LDH term includes a group of LDHs with Li/Al octahedral double hydroxyl layers. We have demonstrated a modifed method, using Li/Al LDH-OH (OH− as interlayer anions) as the starting material, for preparing Li/Al LDH-X (X represents interlayer anions, including dioctyl sulphosuccinate (DOSS), dodecyl sulphate (DDS), mercaptoacetate (MA), EDTA, Tiron and dichromate) under mild acid conditions (pH in the range 4 to 5). However, in the case of acidsensitive anions, Fe(CN)64−, Li/Al LDH-Fe(CN)64− can be prepared by a two-step procedure using Li/Al LDH-DOSS or similar compounds as intermediates to react with acid-sensitive anions under mild alkaline conditions (pH ≈ 9).
