Thiophene substituted benzo[1,2-b:4,5-b′]dithiophene (BDT-T) is widely used as the building block of promising donor materials in organic solar cells (OSCs). Fluorination on the lateral-chain thiophenes of BDT-T is a considerable...
Non-fullerene acceptors have received a great deal of attention over the past several years, and numerous modifications on the molecular structures significantly boosted the power conversion efficiencies (PCEs). To be...
A new heterocyclic aromatic structure, thieno[3,2-c]quinolin-4(5H)-one (TQO), was designed and synthesized as an electron-accepting building block for donor–acceptor-type copolymers.
A new electron acceptor building block, [2,2′-bithiophene]-4,4′-dicarboxamide, is synthesized and used to develop donor polymers for organic solar cells.
In this communication, a novel asymmetric ladder-type thiophene-phenylene-thieno[3,2-b]thiophene-fused building block TPTT and the corresponding asymmetric nonfullerene acceptor TPTT-IC were reported for the first time.
