Abstract

New 5-(4-bromophenyl)-3,7,12,13,17,18-hexamethyl-2,8-dipentyl- and 5,15-bis(4-bromophenyl)-2,8,12,18-tetramethyl-2,8,12,18-tetrapentylporphyrins (H2P-1 and H2P-2) and their zinc metal complexes (ZnP-1 and ZnP-2, respectively) were synthesized in high yields by condensation of β-tetraalkyl-substituted dipyrromethanes with 2-formyl-3,4-dialkylpyrroles or 4-bromobenzaldehyde and subsequent metallation. X-ray analysis data showed the formation of axial complexes of ZnP-1 and ZnP-2 with the solvent molecules of THF and dioxane in the solid state. Coordination of ZnP-1 with dioxane led to polymer multidecker structures.
