PDPP4T (CAS number 1267540-03-3) is a promising class of semiconducting polymers for organic solar cells. This is due to its small optical band gap and high charge-carrier mobility. It is also known as Poly[2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione -3,6-diyl)-alt-(2,2’;5’,2’’;5’’,2’’’-quaterthiophen-5,5’’’-diyl)] or DPP4T.

PDPP4T from Ossila was used in the high-impact paper (IF 14.92), Tuning charge transport dynamics via clustering of doping in organic semiconductor thin films, C. Boyle et al., Nat. Commun., 10, 2827 (2019); DOI: 10.1038/s41467-019-10567-5.

With one DPP unit as electron-withdrawing and four five-membered thiophene as electron-rich units in its backbone, PDPP4T is a low-band gap polymer semiconductor with a planar structure. The alkyl chain attached to the DPP unit serves as a high-solubilising group and has a tendency to crystallize to ensure a better packing film. A hole mobility greater than 1 cm²V^-1s^-1 [8] has been reported in top-contact bottom-gate devices.

Device performance PCE of 7.59% with a V_OC of 0.61 V, J_SC of 17.95 mA/cm ² , and FF of 69.6%, is reported with PC₇₁BM as electron acceptor [1]. This is using a solvent swelling assisted sequential deposition (SSA-SD) method to produce bulk heterojunction PSCs based on a crystalline diketopyrrolopyrrole (DPP) polymer and PC₇₁BM. By adding polymers with high mobility, like DPP-DTT, device performance with higher PCE should be expected [5].

Characterization

Soxhlet extraction was carried out using methanol, acetone, hexane, and then chlorobenzene as washing solvents under argon. Chlorobenzene fraction was concentrated, precipitated with methanol, and dried under vacuum at 40 ^oC for 48 hours. GPC was carried out using 1,2,4-trichlorobenzene as eluent at 140 ^oC by using polystyrene as standards.

Synthetic Route

DPP4T was synthesized by using 3,6-bis(5-bromothiophen-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 via Stille Coupling polymerisation in chlorobenzene. Targeted polymer was purified using Soxhlet extraction with methanol, acetone, hexane and finally chlorobenzene as washing and extracting solvents.
