DPP-BO-2ThBr, for the synthesis of low band-gap semiconducting polymers

High purity monomer for applications in OFETs and solar cells


Specifications | MSDS | Literature and Reviews


3,6-bis(5-bromothiophen-2-yl)-2,5-bis(2-butyloctyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione (DPP-BO-2ThBr), CAS number 1224709-68-5, is used for the synthesis of low band-gap polymer semiconductors (such as PBDTT-DPP) for OPV and perovskite solar cell applications.

DPP-BO-2ThBr is also used as an intermediate for the synthesis of small molecules, and as an electron-donor material for applications in OFETs and solar cells.

This product has been used in our own lab for the synthesis of PBDTT-DPP.
