Preparation of a Layered Double Hydroxide–Porphyrin Intercalation Compound

Abstract
5,10,15,20-tetra(4-sulfonatophenyl)porphin (TSPP) is intercalated into the interlayer space of hydrotalcite by anion exchange. The intercalated porphyrin anions are possibly arranged with the molecular plane perpendicular to the hydroxide layers.
