High purity IDTTB6-2Sn available to buy online

Intermediate for the synthesis of non-fullerene acceptors or low bandgap semiconducting polymers


6,6,12,12-tetrakis(4-hexylphenyl)-s-indacenodithieno[3,2-b]thiophene-bis(trimethylstannane) (IDTTB6-2Sn), or 6,6,12,12-tetrakis(4-hexylphenyl)-s-indacenodithieno[3,2-b]thiophene-bis(trimethylstannane), is an useful intermediate for the synthesis of either non-fullerene acceptors (NFAs) or low bandgap semiconducting polymers. Polymer L1057 nanoparticles, which are used for NIR-II bioimaging-guided photothermal cancer therapy, has IDTTB6-2Sn as one of its building blocks [2].

IDTTB6-2Sn has a fused indacenodithieno[3,2-b]thiophene (IDTT) back-bone with out-of-plane hexylphenyl side chains. Trimethylstannyl end functional groups provide access to C-C formation via Stille coupling reaction.

Part of our range of non-fullerene acceptor monomers, high purity (>98%) IDTTB6-2Sn is available for priority dispatch (lead times may apply for large quantities) and qualifying orders ship free.
