Optical self-defocusing, characterized by the non-linear refractive index n~2~, was investigated by the Z-scan technique in water solutions of two porphyrins (PPhs), negatively charged meso-tetrakis(p-sulfonatophenyl)porphyrin ( TPPS ~4~) and positively charged meso-tetrakis(4-N-methyl-pyridiniumyl)
