Uses

Different sources of media describe the Uses of 159-66-0 differently. You can refer to the following data:
1. A blue light emitting material in organic light emitting diodes (OLEDs). Also used as a blue-emitting material in electroluminescent devices.
2. 9,9′-Spirobifluorene can be used in the synthesis of spirobifluorene based conjugated microporous polymers which can be potentially be used as a gas absorbent. It may be used as a hole transporting material which can be used in the fabrication of perovskite solar cells.

General Description

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.
