Description	Solid meso-tetrakis(4-sulphonatophenyl)porphyrin (TPPS4) ? chitosan supramolecular complexes were prepared by addition of porphyrin to an aqueous solution of chitosan at different pH. The precipitates obtained were assigned as 1 (pH 6.8) and 2 (pH 2.5) and characterized by spectroscopic methods (Vis-NIR, FT-IR, Raman and NMR), thermal (TG/DTG and DSC) and image analysis (LM, SEM and AFM). Spectroscopic investigation confirmed the presence of TPPS4 and chitosan in both products and that the porphyrin is highly self-associated. H-type (stacked) of TPPS4 aggregation was proposed for 1 and J-type (tilted) for 2. Thermal analysis revealed different pyrolysis routes of the complexes depending on their structural diversity. Light microscopic images indicated fibrous and lamellar microstructures, respectively for 1 and 2. SEM and AFM images showed that both complexes consist of disk-like nanostructures; the size and interconnection of the discs is different for 1 and 2. Based on structural inferences, self-as Solid meso-tetrakis(4-sulphonatophenyl)porphyrin (TPPS4) ? chitosan supramolecular complexes were prepared by addition of porphyrin to an aqueous solution of chitosan at different pH.
