The Construction of H-shaped Fluorescent Materials Based on Building Blocks Consisting of Triphenylamine and Fluorene

A class of complicated 9,9-diarylfluorenes as nonplanar building blocks were synthesized and utilized to prepare a novel H-shaped oligofluorene. High glass transition temperatures and excellent solubility of the obtained oligomers indicated the 9,9-diarylfluorenes would be promising building blocks for the construction of H-shaped optoelectronic materials.
