(5Z,5'Z)-5,5'-((7,7'-(4,4,9,9-tetraoctyl-4,9-dihydro-s-indaceno[1,2-b:5,6-b']dithiophene-2,7-diyl)bis(benzo[c][1,2,5]thiadiazole-7,4-diyl))bis(methanylylidene))bis(3-ethyl-2-thioxothiazolidin-4-one) CAS NO.2077945-91-4

o-IDTBR demonstrates an acceptor-acceptor–donor–acceptor-acceptor (A-A'–D–A'-A) structure consisting of an electron-donating ladder-type fused five-member-ring indaceno[1,2-b:5,6-b′]dithiophene (IDT) core with aliphatic n-octyl side chains, flanked by two electron withdrawing benzothiadiazole moieties and rhodanine terminated groups.

With a maximum absorption around 600 - 730 nm and reduced charge recombination losses, the small molecule acceptor has been widely used as an n-type non-fullerene acceptor (NFA) in polymer organic photovoltaics for its promising stability under ambient conditions and outstanding photovoltaic performance.
 

We have sublimation apparatus

When PTB7-Th was used as the low band-gap donor polymer, mixed acceptors of o-IDTBR and o-IDFBR demonstrated a great device performance with 11.0 ± 0.4% efficiency and a high open-circuit voltage of 1.03 ± 0.01.
