OLIGOMERIC PERYLENE DIIMIDE NON-FULLERENE ACCEPTORS VIA DIRECT (HETERO) ARYLATION CROSS-COUPLING REACTIONS

摘要

Oligomeric compounds useful as organic conjugated materials in electronicdevices.Oligomeric compounds contain three or more or four or more of certain PDIunits bonded toan organic core. The organic core contains one, two or more thiophene rings.The organiccore can contain two or more thiophene rings separated by a linker group; twoor morethiophene rings directly fused to each other or indirectly fused to each otherthrough anoptionally substituted aromatic or non-aromatic carbocylic ring system or anoptionallysubstituted aromatic heterocyclic or non-aromatic heterocyclic ring system; oreach of two ormore thiophene rings is fused to an aromatic or non-aromatic carbocylic ringsystem or anaromatic heterocyclic or non-aromatic heterocyclic ring system and theresulting fused ringscontaining a thiophene ring are each separated by a linker group M. Methodsfor makingoligomeric compounds by direct heteroarylation are provided..
