IDTB6-2Sn, high purity monomer

An intermediate in polymer organic solar cells for low band gap polymers and NFAs

4,4,9,9-tetrakis(4-hexylphenyl)-4,9-dihydro-s-indaceno[1,2-b:5,6-b']dithiophene-2,7-diyl)bis(trimethylstannane) (IDTB6-2Sn) has a structure of four hexylphenyl groups attached to an indaceno[1,2-b:5,6-b']dithiophene (IDT) core. IDTB6-2Sn has trimethylstannyl end functional groups for Stille coupling reaction to further extend its conjugation and enable absorption into the near-infrared region.

In polymer organic solar cells, IDTB6-2Sn is used as an intermediate for more complicated structures such as low bandgap polymers or non-fullerene acceptors, such as IDT-2Br or IEICO-4F.

Part of our range of non-fullerene acceptor monomers, we stock high purity (>98%) IDTB6-2Sn for priority dispatch (lead times may apply for large quantities, please contact us for details). Qualifying orders ship free.
