Synthesis, characterization and properties of a novel soluble polyester based on fluorine

摘要

Fluorene and its derivatives which have an aromatic biphenyl structure with wide energy gap in the backbone and high luminescent efficiency have been drawn much attention to materials chemists and device physicists. In this research, 9,9-Bis(methoxycarbonylethy)fluorene and fluorene-containing polyester were prepared and their chemical structure and properties were initially studied. Furthermore, It is found that this fluorene-containing polyester might be a promising candidate for electroluminescent materials due to its excellent luminescent properties, solubility, film-forming property and thermal stability.
