Used primarily in organic synthesis and materials science, this compound serves as a building block for conjugated systems in the development of organic semiconductors and optoelectronic materials. Its extended π-conjugated structure makes it suitable for applications in organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). The ethynyl linkage enhances electron delocalization, improving charge transport properties. It is also employed in the synthesis of liquid crystals and nonlinear optical materials due to its rigid, planar geometry and tunable electronic characteristics. Additionally, it finds use in research settings for constructing molecular frameworks in supramolecular chemistry.
