Abstract
Oligomeric compounds useful as organic conjugated materials in electronic devices. Oligomeric compounds contain three or more or four or more of certain PDI units bonded to an organic core. The organic core contains one, two or more thiophene rings. The organic core can contain two or more thiophene rings separated by a linker group; two or more thiophene rings directly fused to each other or indirectly fused to each other through an optionally substituted aromatic or non-aromatic carbocylic ring system or an optionally substituted aromatic heterocyclic or non-aromatic heterocyclic ring system; or each of two or more thiophene rings is fused to an aromatic or non-aromatic carbocylic ring system or an aromatic heterocyclic or non-aromatic heterocyclic ring system and the resulting fused rings containing a thiophene ring are each separated by a linker group M. Methods for making oligomeric compounds by direct heteroarylation are provided.
