Descrizione generale

Fluorene is a rigid, planar polycyclic aromatic hydrocarbon. White crystals of fluorene have violet fluorescence, from which its name derives. It is used as a precursor to other fluorene compounds. Fluorene is used as a chemical intermediate in the formation of polyradicals for resins as well as the manufacture of resinous products and dyes.

Applicazioni

Fluorene was used study the extraction of specific, semiconducting single-wall carbon nanotubes (SWCNTs).

Caratteristiche e vantaggi

As a monomer, fluorene exhibits significant solubility while maintaining a high degree of delocalization.

To understand how fluorene-based polymers selectively extract specific semiconducting single-wall carbon nanotubes (SWCNTs), we compared the optical transitions of SWCNTs wrapped with poly(9,9-dioctylfluorene-alt-pyridine) (PFOPy), i.e., structure-selective polymers, with those wrapped with poly(9,9-di-n-dodecylfluorene) (PFD), i.e., non-selective polymers, in organic solvents by

A highly gas-permeable polymer with enhanced selectivities is prepared using spirobifluorene as the main structural unit. The greater rigidity of this polymer of intrinsic microporosity (PIM-SBF) facilitates gas permeability data that lie above the 2008 Robeson upper bound, which is
