简单介绍


ossila材料o-IDTBR  的详细介绍

o-IDTBR, CAS number 2077945-91-4, is a small molecule acceptor which demonstrates an acceptor-acceptor–donor–acceptor-acceptor (A-A'–D–A'-A) structure. This consists 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 at around 600 – 730 nm and reduced charge recombination losses, o-IDTBR has been widely used as an n-type non-fullerene acceptor (NFA) in polymer organic photovoltaics. Among its useful properties, it shows promising stability under ambient conditions and exhibits outstanding photovoltaic performance.

Using PTB7-Th as the low band-gap donor polymer, mixed acceptors of o-IDTBR and o-IDFBR have demonstrated impressive device performance. An efficiency of 11.0 ± 0.4% and a high open-circuit voltage of 1.03 ± 0.01 has been reported.
