Descrição geral

2,7-Dibromofluorene is a halogenated polycyclic aromatic compound and its vapour pressure has been measured using the Knudsen effusion method.

Aplicação

2,7-Dibromofluorene was used as a template for the N-carbazole capped oligofluorenes which show potential as hole-transporting materials for organic light emitting devices (OLEDs). It may be used in the synthesis of conjugated polymer, poly[9,9′-bis(6′′-N,N,N-trimethylammonium)hexyl)fluorene-co-alt-4,7-(2,1,3-benzothiadiazole) dibromide] (PFBT), used in label-free DNA microarrays. It was used in the preparartion of blue photoluminescent unsymmetrically substituted polyfluorene. It was also used in the preparation of 2,7-dibromofluorene monomers containing benzyl ether dendrons (generations 1, 2 and 3) in the 9,9′-position of the fluorene ring, such as:
  • 9,9-bis[(3,5-bis(benzyloxy)benzyloxy)methyl]-2,7-dibromofluorene
  • 9,9-bis[(3,5-bis(3,5-bis(benzyloxy)benzyloxy)benzyloxy)-methyl] 2,7-dibromo-fluorene
  • 9,9-bis[(3,5-bis(3,5-bis(3,5-bis(benzyloxy)benzyloxy)benzyloxy) benzyloxy)-methyl]-2,7-dibromofluorene

The first unsymmetrically substituted polyfluorene bearing a bulky poly(benzyl ether) dendron and less bulky 3,6-dioxaoctyl groups in the 9-position was designed and synthesized, which gives almost a pure bluish photoluminescence with negligible weak greenish excimer emission around 520 nm even

The synthesis and characterization of complex dendritic, rigid rod poly-2,7-fluorene homopolymers and copolymers via a macromonomer approach is reported. Several 2,7-dibromofluorene monomers containing benzyl ether dendrons (generations 1, 2, and 3) in the 9,9'-position of the fluorene ring were prepared

We describe the synthesis of poly[9,9'-bis(6''-N,N,N-trimethylammonium)hexyl)fluorene-co-alt-4,7-(2,1,3-benzothiadiazole) dibromide] (PFBT), a cationic, water-soluble conjugated polymer used in label-free DNA microarrays. This polymer was designed to have a maximum absorbance of close to 488 nm, which meets the excitation wavelength of most commercial
