2-(5,6-dichloro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile is also named 2ClIC. It is similar to 2HIC and 2FIC, both are strong electron-withdrawing molecules. It can be used as electron-withdrawing acceptors to connect with donor to form acceptor–donor–acceptor (A–D–A)-type acceptor materials for the preparation of organic solar cells (OSCs)[1-2].
2-(5,6-Dichloro-2,3-dihydro-3-oxo-1H-inden-1-ylidene)propanedinitrile is a chlorinated fused nonacyclic non-fullerene acceptor enables efficient large-area polymer solar cells with high scalability.
