Thiophene-fused dithiaoctaphyrins: π-system switching between cross-conjugated and macrocyclic π-networks

Abstract

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.
