We synthesized for the first time octaphyrins with a dithieno[3,4-b:3′,4′-d]thiophene core as thiophene-fused dithiaoctaphyrins with a cross-conjugated structure. The octaphyrins revealed cross-conjugated and macrocyclic 36π-electron networks.

Simple conditions are discovered to afford modified tripyrrin derivatives by condensation of 2,5-bis(α-hydroxymethyl)pyrrole, thiophene and furan derivatives with pyrrole in the presence of acid catalyst. The core-modified porphyrins were synthesized by acid catalyzed 3+1 condensation of modified tripyrrins with 2,5-bis(α-hydroxymethyl)-substituted pyrrole, thiophene or furan. This new process gives a single porphyrin isomer and overcomes the synthetic problems associated with separation and purification of regioisomeric mixtures.
