High purity and available online for priority dispatch
Poly(2,5-bis(2-octyldodecyl)-3,6-di(pyridin-2-yl)-pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione-alt-2,2’-bithiophene) (DPPDPyBT), CAS number 1455028-36-0, is a good electron transporting material used in the application of OFETs and OPVs.
PDBPyBT (DPPDPyBT, high-mobility n-type polymer) from Ossila was used in the high-impact paper (IF 10.51), Versatile Interpenetrating Polymer Network Approach to Robust Stretchable Electronic Devices, G. Zhang et al., Chem. Mater., 29, 18, 7645–7652 (2017); DOI: 10.1021/acs.chemmater.7b03019. Synergistic Use of Bithiazole and Pyridinyl Substitution for Effective Electron Transport Polymer Materials, C. Buckley et al., Chem. Mater., 31, 11, 3957–3966 (2019); DOI: 10.1021/acs.chemmater.9b00208.
DPPDPyBT contains a DPP unit which has been found to be an excellent electron accepting moiety for a large number of polymer semiconductors for OTFTs, OPVs and OLEDs. DPPDPyBT has been proven to have a planar structure, together with two five-membered rings having six π-electrons being shared, an electron rich moiety with DPP and two pyridyl units being excellent electron withdrawing ability, resulting in DPPDPyBT being an excellent candidate as an electron transporting material.
As one of promising high charge carrier mobility polymers (electron and hole mobility up to 6.3 cm2V-1s-1 and 2.78 cm2V-1s-1 respectively, has been reported [1]), these type of polymers are also used as blending material (low ratio) for OPV devices to facilitate electron collection from the active layer to PCBMs [2].
PDBPyBT, a high-mobility n-type polymer, is now back in stock with higher molecular weight.

Chemical Structure
Synthetic Route
PDBPyBT was synthesised engaging Stille Coupling reaction with 3,6-Bis(5-bromopyridin-2-yl)-2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione and 5,5′-bis(trimethylstannyl)-2,2-bithiophene as starting materials in chlorobenzene as solvent. Polymer was purified by Soxhlet extraction with methanol, acetone, hexane and chlorobenzene as washing and extracting solvents.
