Applications

ITIC-DM, another family member of ITIC, is used as an acceptor material to replace fullerene for high-performing organic solar cells (NFA-OSC).

Due to the electron-donating nature of the methyl groups at the end benzene rings, ITIC-DM has higher HOMO/LUMO energy levels compared those of ITIC or ITIC-M. Extra methyl groups also have the potential to help enhance solubility and film morphology for material processing and device fabrication.
