Two simple water-soluble meso-substituted porphyrins were ion-exchanged int the interlayer space of montmorillonite, hectorite, and fluorhectorite. The porphyrins studied were the chloride salts of tetrakis(1-methyl-4-pyridiniumyl)porphyrin (TMPyP) and tetrakis(N,N,N-trimethyl-4-aniliniumyl)porphyrin (TAP) and the corresponding metalloporphyrins Fe{sup III}tap, Fe{sup III}TMPyP, and Co{sup II}TMPyP. These were ion-exchanged into H-, Li-, Na-, Ca-, Cu-, Co-, VO-, and Fe-montmorillonites and fluorhectorites. The porphyrins are diprotonated in H- and transition-metal-ion-exchanged clays.
