Two tri(benzo[ b ]thiopheno)subporphyrazine regioisomers with C 3 and C 1 molecular symmetry have been isolated from the cyclotrimerization of benzo[ b ]thiophene‐2,3‐dicarbonitrile as the first five‐membered‐heterocycle‐fused subphthalocyanine analogues. Optical resolution of both regioisomers was achieved by using a chiral HPLC technique, affording the first chiral subphthalocyanine analogues.
