摘要：

Novel fluoroarylporphyrins bearing electron donor dimethylamino groups in the meso-aryl positions and an electron acceptor nitro group on one of the pyrrole carbons exhibit significant solvent dependent fluorescence spectra and time-resolved emission properties. These effects are suggestive of intramolecular charge transfer (ICT) in the singlet excited state of these porphyrins. Electrochemical redox behaviour of these porphyrins showed the presence of substantial donor-acceptor interactions in the nitro-amino porphyrins.
