General description
Tetrafluoroterephthalonitrile reacts with alkyl Grignard reagents to form corresponding 4-alkyltetrafluorobenzonitriles. Tetrafluoroterephthalonitrile acts as a four-electron donor ligand and forms tungsten(II)η2-nitrile complexes.
Application
Tetrafluoroterephthalonitrile can be used in the synthesis of Polymers of Intrinsic Microporosity (PIM). Tetrafluoroterephthalonitrile was used to study ultraviolet (UV)-rearranged polymers of PIM-1 membranes for efficient separation of H2 and CO2 .

Polydopamine-modified additives have been thus far widely used in the mixed matrix membranes (MMMs) for gas separation. However, very few reports focus on the polydopamine alone and investigate its contribution to the gas separation performance. Herein, the polydopamine-derived submicrospheres (PDASS)
