CAS Number 2047352-92-9
ITIC-DM (CAS number 2047352-92-9), a family member of ITIC, is used as an acceptor material to replace fullerene acceptors in high-performing organic solar cells (NFA-OSC). Non-fullerene acceptors like ITIC-DM offer a number of advantages over fullerene and fullerene derivatives, promising higher power conversion efficiencies (PCEs) and longer device lifetimes.
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.
