The effect of charge density of clay on porphyrin-saponite complexes

Abstract

We found that a high density of porphyrin molecules were adsobed onto the clay layers without aggrigation. This depends on size-matching of distance between the charge sites (Size-Matching Effect). Porphyrin-clay complexes have been studied with various porphyrins. In this research, the adsorption behavior was investigated with artificially synthesized saponites that have difference distance between the charge sites.
