TCI B5656 (CAS 728911-52-2) is a spirobifluorene-based organoboron reagent featuring two pinacol boronate ester groups, making it an excellent building block for Suzuki-Miyaura cross-coupling reactions. Its rigid, orthogonal spirobifluorene core imparts high thermal stability and effectively suppresses intermolecular aggregation, which is highly desirable in organic optoelectronic applications. This compound is widely employed in the synthesis of OLED materials, fluorescent sensors, organic semiconductors, and porous organic frameworks.
