A new route of water soluble porphyrins: phosphonium and ammonium type cationic porphyrins and self-assembly

Abstract

From a precursor porphyrin, tetrakis(p-chloromethylphenyl) porphyrin, the novel phosphoniumyl and ammoniumyl cationic porphyrins are synthesized, and the unusual spontaneous assembly for the two cationic porphyrins is discussed.
