Here we present the way of synthesis of very stable J-aggregates based on water-soluble 2-N-methyl-5,10,15,20-tetrakis-(4′-sulfophenyl)-2-aza-21-carbaporphyrin zwitter-ion, which are formed as the main product of 2-N-methyl-5,10,15,20-tetraphenyl-2-aza-21-carbaporphyrin sulfonation by sulfuric acid. J-Aggregates and corresponding monomer were obtained for the first time and characterized using UV-Vis, 1H NMR, MALDI-TOF, ESI-MS analysis.
