IDTB6-2Br, for further synthesis of conjugated polymers and non-fullerene semiconductors

High quality and expert support available online

2,7-Dibromo-4,9-dihydro-4,4,9,9-tetrakis(4-hexylphenyl)-s-indaceno[1,2-b:5,6-b']dithiophene (IDTB6-2Br), CAS number 1049034-71-0, has a fused indaceno[1,2-b:5,6-b']dithiophene (IDT) core with four hexylphenyl side chain groups to enhance its solubility in common organic solvents. With end bromine functional groups, IDTB6-2Br can be used as intermediates or building blocks for further synthesis of conjugated polymeric or non-fullerene semiconductors for OLED, OFET and OPV applications.

Part of our range of non-fullerene acceptor monomers, we stock high purity (>98%) IDTB6-2Br for priority dispatch (lead times may apply for large quantities). Free shipping is available on qualifying orders.
