(BF3OEt2)-O-.-mediated Friedel-Crafts reaction of 9-phenyl-fluoren-9-ol with electron-rich aromatic substrates to prepare a new family of complicated 9,9-diarylfluorenes is described. The 9,9-diarylfluorenes tethered with various functional substituents, e.g., bulky spiro units, hole-transporting moieties, and fluorescent dyes, will be promising building blocks for the construction of optoelectronic materials.
文中描述了以 (BF3OEt2)-O- 为介导剂,通过 Friedel-Crafts 反应将 9-苯基芴-9-醇与电子丰富的芳香底物反应,制备出一类结构复杂的 9,9-二芳基芴。这些 9,9-二芳基芴带有多种功能取代基,例如大位阻的螺环结构、空穴传输基团和荧光染料,有望成为构建光电材料的理想构建模块。
