Description and Uses

2-Ethylhexyl 4,6-Dibromo-3-fluorothieno[3,4-b]thiophene-2-carboxylate has been used for the synthesis low band gap polymer semiconductors such as PTB-7?and PCE10 (also called PTB7-Th or PBDTTT-EFT) for OFETs, OLED, PLED?and OPV applications.

2-Ethylhexyl 4,6-dibromo-3-fluorothieno[3,4-b]thiophene-2-carboxylate (TTF) can be used in the synthesis of diketopyrrolopyrrole (DPP) based low band polymers for the fabrication of organic field-effect transistors (OFETs). It can also be used in the synthesis of narrow band-gap polymers like PBDTT-OS-TT-EF (1.52 eV) and PBDTT-OS-TT-CF (1.56 eV) for polymeric solar cells.
