3,3'-Difluoro-5,5'-bis(trimethylstannyl)-2,2'-bithiophene (CAS number 1619967-09-7) is used for the synthesis of small molecules or polymer semiconductors in organic electronic applications, such as P(NDI2OD-T2F).
It is believed that, by introducing heteroatoms such as fluorine on the backbone of polymer structures, the crystalline properties of the conjugated polymers can be enhanced, resulting in a higher degree of orientation of such polymer structures with optimised domain size in blended thin films with either fullerene or non-fullerene acceptors.
This product has been used in our own lab by Ossila chemists for the synthesis of PBDD4T-2F.
