Used as a key building block in organic semiconductor materials, particularly in the production of high-performance polymers for OLED (organic light-emitting diode) displays and lighting. Its rigid, planar structure enhances electron stability and improves charge transport in electronic devices. Also employed in the synthesis of conjugated polymers and dendrimers for optoelectronic applications due to its excellent thermal and oxidative stability. Additionally, it serves as a precursor in pharmaceuticals and agrochemicals where fused aromatic systems are required.
