文摘
- •
A1-D-A2-D-A1-type conjugated molecules were firstly demonstrated.
- •
Three conjugated molecules containing DPP and another weaker acceptor were synthesized.
- •
Thiophene carboxylate (3EhT), thienopyrroledione (TPD), and fluorinated thienothiophene (TT) were employed.
- •
(TPD)(DPP)2 exhibited the highest power conversion efficiency of 3.37%.
