Benzo[k]tetraphene is primarily used in organic electronics due to its extended π-conjugated structure. It serves as a building block in the development of organic semiconductors, particularly in organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). Its rigid, planar framework enhances charge carrier mobility, making it valuable for high-performance electronic devices. Additionally, it is studied in the design of novel polycyclic aromatic hydrocarbon (PAH)-based materials for optoelectronic applications and as a precursor in synthesizing larger graphene-like structures. Its photophysical properties also make it suitable for use in fluorescent sensors and dyes.
