Used as a powerful Lewis acid catalyst in organic synthesis, particularly in frustrated Lewis pair (FLP) chemistry for activating small molecules like hydrogen and carbon dioxide. Facilitates metal-free hydrogenation reactions of imines, enamines, and unsaturated hydrocarbons. Employed in polymerization processes, including the catalytic formation of polyolefins. Acts as a dopant in organic electronics due to its electron-accepting properties, enhancing conductivity in semiconductor materials. Shows utility in sensing applications because of its ability to bind Lewis bases and fluorophores. Also applied in the development of boron-containing functional materials and supramolecular systems.
