A blue light emitting material in organic light emitting diodes (OLEDs). Also used as a blue-emitting material in electroluminescent devices.
?? ??
9,9′-Spirobifluorene is a polyfluorene with carbon atoms of the methylene bridge connected to two fluorene molecules. It is mainly used in organic electronics due to its robust structure and two perpendicularly arranged π systems.
