ITIC-M, a family member of ITIC, is a non-fullerene, small-molecule acceptor that is used for high-efficiency polymer solar cells. ITIC acceptors have the benefit of strong and broad absorption (from visible to near infrared) with good alignment of energy levels to the low band-gap polymer semiconductors.

Being slightly more electron-rich than ITIC, ITIC-M has a higher energy level with an elevated LUMO level to increase Voc for OPV devices, thus improving the overall power conversion efficiency (PCE). Methyl groups on the phenyl rings also increase the solubility of the structure, and help ITIC-M to have greater miscibility with the polymer donors.

ITIC-M, ITIC-Th, ITIC- 2F, and ITIC from Ossila were used in the high-impact paper (IF 18.81), Polymorphism in Non-Fullerene Acceptors Based on Indacenodithienothiophene, S. Marina et al., Adv. Funct. Mater., 2103784 (2021); DOI: 10.1002/adfm.202103784.

We also have ITIC-DM available as an alternative dimethyl substituted NFA for high efficiency NF-PSCs.
