High purity DPP-EH-2ThBr monomer

For the synthesis of small molecules and low band gap semiconducting polymers


Specifications | MSDS | Literature and Reviews


3,6-bis(5-bromothiophen-2-yl)-2,5-bis(2-ethylhexyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione, DPP-EH-2ThBr (CAS number 1000623-95-9), is a building block containing a DPP backbone as a strong acceptor unit. It has a planar conjugated bi-cyclic structure engaging stronger π–π interactions. Due to its electron-deficient nature, DPP-EH-2ThBr and its derivatives are used for the synthesis of small molecules and low band-gap polymer semiconductors with OPV, OLED and perovskite solar cells.
