Used primarily in organic electronics, this compound serves as a key intermediate in the synthesis of high-performance materials for organic light-emitting diodes (OLEDs). Its rigid spirobifluorene structure enhances thermal stability and reduces molecular aggregation, making it ideal for blue-emitting host materials. The iodo functional group allows for easy cross-coupling reactions, enabling the construction of complex conjugated systems used in hole-transport layers and host materials in phosphorescent OLEDs. It is also employed in the development of thermally activated delayed fluorescence (TADF) emitters and as a building block for metal-organic frameworks with optoelectronic properties.
