The symmetric meso-tetrakis(4-aminophenyl)porphyrin was reacted with nonstoichiometric amount of N,N′-bis(tert-butoxycarbonyl)-S-methylisothiourea with respect to the amine functions of the porphyrin to afford (after deprotection of the Boc residues) the asymmetric guanidiniumphenyl-aminophenyl porphyrins carrying two or three guanidiniumphenyl substituents at the meso-position. The adjacent and opposite isomers of the bis(guanidiniumphenyl) modified porphyrins were isolated separately.
