Synthesis of a novel fluorene derivative for polyfluorenes: 7,7'-di(5-bromothiophen-2-yl)-9,9,9',9'-tetraoctyl-2,2'-bifluorene

摘要

A new bifluorene derivative, 7,7'-di(5-bromothiophen-2-yl)-9,9,9',9'-tetraoctyl-2,2'-bifluorene, has been prepared over six steps. The compound with good solubility, electronic and optical properties may be a candidate for polyfluorenes and copolymers of fluorenes.
