Used as a key building block in the synthesis of porous organic polymers and covalent organic frameworks (COFs), enabling applications in gas storage, catalysis, and optoelectronic materials due to its rigid tetrahedral structure and reactive ethynyl groups. The compound’s multiple alkyne functionalities allow for efficient cross-linking via click chemistry or Sonogashira coupling, making it valuable in constructing well-defined 3D networks for advanced material design. Also explored in surface functionalization and thin film fabrication for sensor development.
