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 .
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.
