Immobilization of a cationic manganese(III) porphyrin on lithium gordaite (LiZn4(OH)(6)(SO4)Cl center dot 6H(2)O), a layered hydroxide salt with cation exchange capacity

摘要

Sodium gordaite (NaG - NaZn4(OH)(6)(SO4)Cl center dot 6H(2)O) was synthesized, characterized and the intercalated sodium cations (in hydrated state) of NaG were replaced by lithium where the basal parameter was altered from 13.03 A to 17.84 angstrom. The obtained lithium gordaite (LiG) was used as support for the immobilization of a cationic manganese(III) porphyrin (MnP) on the outer surfaces of the layered crystals. Before and after MnP immobilization, the material was investigated by several instrumental techniques, showing that this class of layered compounds is a new alternative for the immobilization of cationic species for a broad range of potential applications.
