Two dipyrrolo[2,3-b:2′,3′-e]pyrazine-2,6(1H,5H)-dione (PzDP)-based small mols. DPDV and DPEV with PzDP as the core building block and 4,5-dicyano-2-vinylimdazole (vinazene) as end-cap units were synthesized by Heck coupling reaction. The photophys., electrochem. properties of DPDV and DPEV were investigated and applied as non-fullerene acceptors (NFAs) for solution-processed bulk heterojunction (BHJ) organic solar cells (OSCs). Theor. evaluated optical and electrochem. properties were well matched with exptl. values. Solution processed BHJOSCs employing poly[(4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b’]dithiophene-2,6-diyl)-alt-(3-fluoro-2-[(2-ethylhexy)carbonyl]thieno[3,4-b]thiophene-4,6-diyl)] (PTB7) as the donor polymer and DPDV/DPEV as NFAs exhibited short-circuit c.d. (JSC) of 2.23/2.44 mA cm-2, open-circuit voltage (VOC) of 0.54/0.55 V, fill factor (FF) of 36.97/38.62 and power conversion efficiency (PCE) of 0.45/0.52%, resp. In the part of experimental materials, we found many familiar compounds, such as Ethyl oxalyl monochloride(cas: 4755-77-5Recommanded Product: Ethyl oxalyl monochloride)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Recommanded Product: Ethyl oxalyl monochloride
