Used in organic synthesis as a building block for creating boron-containing conjugated materials, particularly in the development of organic light-emitting diodes (OLEDs) and other optoelectronic devices. Its spirocyclic structure enhances thermal and morphological stability, making it valuable in designing host materials for blue phosphorescent OLEDs. The boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, allowing incorporation into larger π-conjugated systems for tailored electronic properties. Also explored in sensor applications due to its potential for selective binding and fluorescence response in the presence of specific analytes.
