Used as an organic semiconductor material in optoelectronic devices, particularly in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid, planar structure and extended π-conjugation enable efficient charge transport and good thermal stability, making it suitable for electron-transport layers or emissive components. The nitrile groups enhance electron affinity, improving electron injection and device performance. Also investigated as a building block in covalent organic frameworks (COFs) for sensing and catalysis due to its redox-active phenazine core.
