High purity BDTT-F-Sn, for applications in highly efficient OSCs and OPVs

For the synthesis of small molecular donors and low band gap semiconducting polymers

2,6-bis(trimethytin)-4,8-bis(5-(2-ethylhexyl)-4-fluorothiophen-2-yl)benzo[1,2-b:4,5-b’]dithiophene (BDTT-FS-n) is an electron-rich building block used for the synthesis of either small molecular donors or low band-gap polymer semiconductors (like PBDB-T-F) for highly-efficient OSCs and OPV applications.

Bearing two ethylhexyl side chains, with fused benzodithiophenes and thiophenes as electron-rich pendants, BDTT-F-Sn offers good solubility for the targeted materials. The introduction of the fluoro atoms on the side thiophene rings can also lower the HOMO/LUMO energy levels of the desired polymers.

Available to purhcase up to 25 g. If you are ordering the item with quantity over 5 g please contact our customer care team for a lead time.
