BrIC, used to synthesise non-fullerene acceptors for highly efficient solar cells

High purity monomer available online with free worldwide shipping on qualifying orders

BrIC, or 2-[5(6)-Bromo-3-oxo-2,3-dihydro-1H-inden-1-ylidene]malononitrile, is a mono-brominated 3-(dicyanomethylidene)indan-1-one that is electron deficient with both carbonyl and malononitrile function groups.

BrIC can be used as an intermediate for the synthesis of non-fullerene acceptors (NFAs) such as TPT10 for highly efficient organic solar cells. Compared to fluorination and chlorination, bromination can more effectively lower the energy levels of the resulting NFA and shift the absorption spectra further into the near-infrared.
