The Pd0- and CuI-catalyzed amination of meso-(halogenophenyl)substituted porphyrins and their Zn complexes with propane-1,3-diamine and trioxadiamine was carried out to produce mono- and diaminated derivatives. Conditions for the synthesis of bis- and trismacrocyclic porphyrin-azacrown conjugates with trimethylenediamine linkers via Pd0-catalyzed amination reactions were established. The properties of two polymacrocyclic compounds to serve as colorimetric and fluorescent sensors for metal cations were investigated, and trismacrocyclic ligand possessing two 1-aza-18-crown-6 moieties arranged symmetrically around the porphyrin core was found to be selective for CuII in the presence of other metals by strong emission quenching caused by copper ions..
