Heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin a pH=7.0 aqueous solution binds meso-tetrakis(4-carboxyphenyl) porphyrin and its zinc complex to yield 2:1 complexes with exceptionally high binding constants. The made of binding, involving the inclusion of two opposite aryl groups in the cyclodextrin cavity, is clearly defined by a detailed NMR analysis.
