Abstract

Strapped porphyrins were prepared directly by the acid-catalyzed condensation reaction of 3, 3′-diethyl-4, 4′-dimethyl-2, 2′-dipyrrylmethane and methylenedioxy bridged dialdehydes having a strap linkage longer than 7 atoms. Dimeric and trimeric porphyrins with coplanar and orthogonal (T-shape) geometries were also synthesized in good yields as an application of this method. In the strapped porphyrins, the distortion of porphyrin ring ...
