Introduction:

Fluorene, or 9H-fluorene, is a polycyclic aromatic hydrocarbon. Fluorene forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. Fluorene is combustible. Fluorene has a violet fluorescence, hence its name. For commercial purposes fluorene is obtained from coal tar,Fluorene is insoluble in water and soluble in many organic solvents.

Application:


Fluorene is widely used as material additive in biological pharmacy, chemical research, chemical synthesis fields and so on.

1)Fluorene is a precursor to other fluorene compounds; the parent species has few applications. Fluorene-9-carboxylic acid is a precursor to pharmaceuticals. 2-Aminofluorene, 3,6-bis-(dimethylamino)fluorene, and 2,7-diiodofluorene are precursors to dyes.

2) Oxidation of fluorene gives fluorenone, which is nitrated to give commercially useful derivatives.

3) 9-Fluorenylmethyl chloroformate (Fmoc chloride) is used to introduce the 9-fluorenylmethyl carbamate (Fmoc) potecting group on amines in peptide synthesis.

4) Polyfluorene polymers (where carbon 7 of one unit is linked to carbon 2 of the next one, displacing two hydrogens) are electrically conductive and electroluminescent, and have been much investigated as a luminophore in organic light-emitting diodes.

5) Cicloprofen is a NSAID 2-arylpropionic acid made from fluorene.
