<jats:title>Abstract</jats:title> <jats:p>20π Antiaromatic isophlorins of N21,N22-bridged N23-alkyl-porphyrins were prepared through photoreduction with N-benzyl-1,4dihydronicotinamide or intramolecular nucleophilic alkylation at the N(24)-position. The ring structure of these N21,N22-bridged isophlorins is not highly deviated from planarity and their antiaromaticity was indicated by the great paramagnetic ring current effect.</jats:p>
