IDT-2Br, like o-IDTBR, has an electron-donating ladder-type fused five-member-ring indaceno[1,2-b:5,6-b′]dithiophene (IDT) core with 4-hexylphenyl side chains, flanked by two electron withdrawing benzothiadiazole moieties and rhodanine terminated groups.
IDT-2Br is a planar electron acceptor when it is compared with o-IDTBR, exhibiting excellent thermal stability, strong and broad absorption, relatively high electron mobility.
When PTB7-Th was used as the low band-gap donor polymer, mixed acceptors of F8IC and IDT-2Br demonstrated a great device performance with 12.1% efficiency
