Abstract
Water-soluble α,β,γ,δ-tetrakis(4-N-methylpyridyl)porphine(TMPyP) was directly intercalated into γ-zirconium phosphate (γ-ZrP) with expansion of the interlayer distance from 12.3 to a maximum of 17.2 A, indicating parallel orientation of porphyrin to the layer of γ-ZrP. Diffuse reflectance spectra of the intercalate shows that the porphyrin is protonated in the interlayer space. Uptake of Cu2+ ions into the porphyrin intercalate takes place with further increase in the interlayer distance. It was observed that TMPyP metalated Cu2+ in γ-ZrP. Copper porphyrin can also be taken up quite easily and an interlayer spacing of 18.6 A is attained.
