Green Light-Emitting Region-Regular Poly(9,9-Dihexylfluorene-co-Fluorenone) Prepared from Solvent-Free Oxidative Coupling Polymerization

摘要

Soluble green light-emitting poly(9,9-dihexylfluorene-co-fluorenone) was synthesized by solvent-free oxidative coupling polymerization of 9,9-dihexylfluorene in a facile one-step reaction. The polymers were characterized by FT-IR, 1H NMR, 13C NMR, UV-Vis and fluorescence spectroscopy. The region-regular structure of the polymer linking at 2, 7′-position on the fluorene moieties was obtained. The FT-IR spectra of the polymers showed fluorenone vibration. The fluorescence spectra of the solid thin film of the polymers displayed green light-emitting, which was emitted from fluorenone moieties produced in the polymerization process.
