Near-infrared two-photon excitation of protoporphyrin IX: photodynamics and photoproduct generation.

R L Goyan1, D T Cramb.   

Abstract

The spectroscopy and photochemistry of protoporphyrin IX in ethanol and in Triton X-100 micelle solution have been examined using near-infrared two-photon excitation (TPE). TPE will allow photodynamic therapy with highly localized light dosage. We have determined that the photochemistry subsequent to TPE is very similar to that found for one-photon excitation. Moreover, the photoproducts observed possess very intense TPE fluorescence spectra, which allows their detection at low relative concentrations.
