Description and Uses
2,2′,7,7′-Tetrabromo-9,9′-spirobifluorene is a spirobifluorene (SBF) derivative and is used as a blue-emitting material in electroluminescent devices. The spirobifluorene linkage in the molecule helps in decreasing the crystallization tendency and also increases the colour stability by preventing the formation of aggregates or excimers. They possess high photoluminescence efficiency and good chemical stability.
2,2'',7,7''-Tetrabromo-9,9''-spirobifluorene is used in the preparation of OLEDs using amorphous compounds with spiro-bifluorene core.
