一般描述

2,7-二溴芴是一种卤代多环芳香族化合物，用 Knudsen 扩散法测定了其蒸汽压。

应用

2,7-二溴芴被用作 N -咔唑封端低聚芴的模板，显示了作为有机发光器件 (OLED) 空穴传输材料的潜力。可用于共轭聚合物聚 [9,9'-双（6'-N,N,N-三甲基铵）己基）芴- co -alt-4,7-（2,1,3-苯并噻二唑）二溴 ] (PFBT)的合成，用于无标记 DNA 微阵列。其已经被用于蓝色光致发光材料不对称取代聚芴的制备。还用于制备在芴环位置9,9'包含苄基醚树枝状分子（第1、2和3代）的2,7-二溴芴单体，例如：
  • 9,9-双[（3,5-双（苄氧基）苄氧基）甲基] -2,7-二溴芴
  • 9,9-双[（3,5-双（3,5-双（苄氧基）苄氧基）苄氧基）甲基] 2,7-二溴芴
  • 9,9-双 [（3,5-双（3,5-双（3,5-双（苄氧基）苄氧基）苄氧基）苄氧基）-甲基]-2,7-二溴芴

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

Knowledge of vapor pressure of organic pollutants is essential in predicting their fate and transport in the environment. In the present study, the vapor pressures of 12 halogenated polycyclic aromatic compounds (PACs), 9-chlorofluorene, 2,7-dichlorofluorene, 2-bromofluorene, 9-bromofluorene, 2,7-dibromofluorene, 2-bromoanthracene, 9-chlorophenanthrene, 9-bromophenanthrene

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
