Fluorene is used in the preparation of dyes such as 2,7-diiodofluorene, 2-aminofluorene and 3,6-bis-(dimethylamino)fluorine as well as resins. It acts as a precursor to other fluorene compounds and to prepare fluorenone. It is utilized in the study of the extraction of specific semiconducting single-wall carbon nanotubes. Its polymer, polyfluorene finds application in electrically conductive and electroluminescent as well as in solar cells. In addition to this, it is used as a luminophore inorganic light-emitting diodes
