一般說明

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.

應用

Blue light emitting material in Organic Light Emitting Diodes (OLEDs).

特點和優勢

High glass-transition temperature, excellent thermal stability, soluble in common organic solvents, multi-layer devices can be fabricated by thermal cross-linking of cast films. Easy colour tunability through the introduction of low band gap co-monomers.
