Abstract

Abstract: A porphyrin host with a preorganized cavity on each face has been synthesized and characterized. The constants for association of the zinc complex of the porphyrin with various amine ligands were determined and compared with those of [meso-tetrakis@- methylphenyl) porphyrinato] zinc (II) and of a “picket-fence” porphyrin zinc (I1) complex. The selectivity for the amine ligands was not observed for the picket-fence porphyrin complex. ...
