Herein we demonstrate the successful photochemical generation of nitric oxide via two-photon excitation (TPE) from the supramolecular complex PPIX−RSE ({μ-S,μ-S‘-protoporphyrin-IX−bis(2-thioethyl)diester]tetranitrosyl-diiron). The TPE fluorescence spectra indicate efficient energy transfer from the PPIX antennae to the iron sulfur nitrosyl cluster. Further evidence of NO release is demonstrated using a nitric oxide specific electrode and ESI+ MS.
