The 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 easy one-step synthesis of a new bis-diaza crown ether porphyrin starting from the widely used αβαβ-tetrakis (o-aminophenyl)porphyrin (TAPP αβαβ) allows access to a new family of potential multisite complexing agents.
