3-(Dicyanomethylidene)indan-1-one (2HIC), CAS number 1080-74-6, is electron deficient thus electron withdrawing. It is used as a building block to prepare non-fullerene acceptors (NFAs) such as ITIC, IHIC, IEIC, IXIC for highly efficient organic photovoltaic devices.

3-(Dicyanomethylidene)indan-1-one can also be used for the synthesis of chromophores which exhibit unique photo-physical properties such large second-order optical nonlinearities.
