Anotace	The arrangement of porphyrin molecules in the interlayer space of layered double hydroxides (LDH) has been studied by a combination of experimental techniques and molecular dynamics simulations. Intercalation of 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrins (TPPS) into ZnRAl and MgRAl LDH hosts led to a gallery height of about 15.5 angstrom that is comparable with the size of the porphyrin molecules. The porphyrin sulfonate groups arc located at about 4 angstrom from the center of the hydroxide layers that is consistent with hydrogen bonding interactions between the sulfonate groups and OH groups of the layers. The aromatic ring system in the middle of the gallery is rather disordered A large number of in-plane diffraction lines suggests that the rigidity of the porphyrin framework has a beneficial effect on the layer ordering.
