High quality and expert support available online
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) 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.
