2,8-Dibromo-6,12-dihydro-6,6,12,12-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2′,3′-d′]-s-indaceno[1,2-b:5,6-b′]dithiophene (IDTTB6-2Br), CAS number 2227361-27-3, is a useful, IDTT cored, intermediate for the synthesis of ITIC series non-fullerene acceptors such as ITIC, ITIC-2F, ITIC-DCl, ITIC-M, ITIC-Th, and ITIC-DM. Such acceptors can be used to create highly efficient polymer organic solar cells.

IDTTB6-2Br has the structure of a highly conjugated fused indacenodithieno[3,2-b]thiophene (IDTT) core with four hexylphenyl attachments oriented almost perpendicularly to the backbone. The introduction of four hexylphenyl groups improves the solubility and degree of crystallinity in the film state.

We stock high purity (>98%) IDTTB6-2Br and a range of other non-fullerene acceptor monomers for priority dispatch (lead times may apply for large quantities). Qualifying orders ship free.
