When compared with ITIC, instead of having phenyl side-chains, ITIC-Th has hexylthienyl side chains which promotes intermolecular interaction - thus the electron mobility induced by sulfur–sulfur interaction.
ITIC-Th from Ossila was 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.
ITIC-Th also shows lower energy levels (HOMO = −5.66 eV, LUMO = −3.93 eV) than ITIC due to the effect of thienyl side-chains. With even deeper energy levels, it can potentially match the energy levels of most of the high-performance narrow, medium, to wide band-gap polymer semiconductor donors.
