3,9-bis(2-methylene-((3-(1,1-dicyanomethylene)-6,7-dichloro)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2',3'-d']-s-indaceno[1,2-b:5,6-b']dithiophene

ITIC-DCl, one of the out-performing ITIC family members, is always used as an acceptor material to replace fullerene in non-fullerene organic solar cells (NFA-OSCs) or?non-fullerene polymer solar cells (NFA-PSCs). When compared with IT-4F (ITIC-2F), ITIC-DM exhibits lower HOMO/LUMO energy levels due to the partial larger dipole moment of the chloro-containing molecules.

ITCI-CI can be mainly used in the fabrication of polymeric solar cells with an efficiency that is less than 11% and excellent thermal stability.

ITCI-CI is a low band acceptor-donor-acceptor molecule with indacenodithieno[3,2‐b]thiophene (IT) as a central donor atom and 2‐(3‐oxo‐2,3‐dihydroinden‐1‐ylidene)malononitrile (IC) as an acceptor end group. It is also a non-fullerene electron acceptor with a push-pull structure that induces an intramolecular charge transfer and extends absorption.
