Nonlinear optical spectroscopy of porphyrins and mesoionic compounds
We report on the! third-order nonlinear optical properties of porphyrins derivatives (PPh) and mesoionic compounds (MIC). The role played by the chemical environment of PPh was investigated and a detailed interpretation is given for the results. Two-photon absorption in MIC was studied and the absorption cross-section was measured in the visible and in the near-infrared.
