Low price, high purity (>98%) ClIC
Synthesise highly efficient non-fullerene acceptors
ClIC, or 2-[5(6)-Chloro-3-oxo-2,3-dihydro-1H-inden-1-ylidene]malononitrile, is used in the synthesis of highly efficient non-fullerene acceptors such as eC9-2Cl. Chlorination usually decreases both the HOMO and LUMO energy levels simultaneously, and leads to a red-shifted spectrum in absorption for the resulting chlorinated non-fullerene acceptor materials.
Like all halogenated 3-(dicyanomethylidene)indan-1-one (2HIC) materials, ClIC, is a mixture of 2-(5-Chloro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (IC-Cl-δ) and 2-(6-Chloro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (IC-Cl-γ).
