We report here the synthesis, characterization, and remarkable shape-selective ligation of silyl ether−metalloporphyrin scaffolds derived from the reaction of 5,10,15,20-tetrakis(2‘,6‘-dihydroxyphenyl)porphyrinatozinc(II) with tert-butyldimethylsilyl chloride, whereby the two faces of the Zn(II) porphyrin were protected with six, seven, or eight siloxyl groups. This results in a set of three porphyrins of nearly similar electronics but with different steric encumbrance around the central metal atom present in the porphyrin. Ligation to Zn by classes of different sized ligands reveals shape selectivities as large as 107.
