fluorenen.

Brit.

/ˈflʊəriːn/,

/ˈflɔːriːn/, U.S.

/ˈflʊˌrin/,

/ˈflɔˌrin/

Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: fluoro- comb. form, -ene comb. form.

Etymology: < fluoro- comb. form + -ene comb. form, after French fluorène (1867 or earlier), named for the violet fluorescence of its crystals. Compare fluor n.¹

Chemistry.

A crystalline tricyclic aromatic hydrocarbon obtained from coal tar and used as a precursor for dyes, pigments, and pharmaceuticals. Also: any substituted derivative of this.Fluorene consists of two benzene rings fused to a cyclopentane ring. Systematic name: o-biphenylenemethane; C₁₃H₁₀.
