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.

Application 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.

Features And Benefits 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.
