Novel diamino and azamacrocycle functionalized porphyrins were efficiently synthesized by palladium-catalyzed amination of mono- and bis(meso-(bromophenyl))porphyrins. The optimization of reaction conditions allowed us to achieve high yields of products with substrates of different types. Supramolecular utility of the thus obtained aminoporphyrins was shown by investigations of processes of coordination self-assembly in solution by NMR and UV-Vis spectroscopy. The crystalline 1D-coordination polymer formed via self-assembly of N,N-dimethylethylenediamine substituted zinc porphyrin was characterized by X-ray diffraction.

AbstractNew 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.

Pd-0-catalyzed amination of 3-bromobenzyl-substituted aza-crown ethers with propane-1,3-diamine affords the 3-(3-aminopropyl)benzyl derivatives, whose reaction with meso-(bromophenyl)-substituted porphyrins leads to bis- and trismacrocyclic conjugates.
