The precipitates obtained were assigned as 1 (pH 6.8) and 2 (pH 2.5) and characterized by spectroscopic, thermal, and microscopic methods. Spectroscopic investigation confirmed the presence of TPPS4 and chitosan in both products and that the porphyrin is highly self-associated. Based on structural inferences, self-assembling hierarchy models were proposed for both of the TPPS4-chitosan supramolecular complexes.
