Abstract

The adsorption of the anionic porphyrin to the surface of solid gold and its remaining fluorescence was reported. Heterodimerization containing a manganese(III) central ion again led to fluorescence quenching of octaanionic meso-tetra(3,5-dicarboxylatophenyl) porphyrin on naked gold. Only the small porphyrin found its way into the compound after it was embedded in a rigid monolayer made of the long-chain thiol. The results showed that three water-soluble molecules can be localized in a water volume of approximately 10 cubic nm.
