Synthesis of a new bis-pyridyl crown-capped porphyrin

International audienceThe synthesis of a new porphyrin bearing both two pyridyl residues and two ortho-nitrophenyl groups in meso position is reported. The reduction of the nitro functions provides the points of anchoring for a crown ether maintained in a cofacial conformation.The synthesis of a new porphyrin bearing both two pyridyl residues and two ortho-nitrophenyl groups in meso position is reported.
