Synthesis and Photophysical Properties of Novel Polystyrene Derivatives Containing Oligofluorene Pendants
A series of novel polystyrene derivatives with oligofluorene pendants were synthesized by Friedel-Crafts reaction. The structure and properties of the polymers and monomers were characterized using NMR, UV-vis spectroscopy, DSC, photoluminescence and electroluminescence spectroscopy. The content of fluorescent units in OPS (oligofluorene grafted polystyrene) was proportional to the dosage of oligofluorene monomers in a wide scope. All the materials were soluble in common organic solvents and easily spin-coated onto the indium-tin oxide(ITO)-coated glass substrates. The polymers showed good fluorescent properties with comparely wide photoluminescent spectra. This method could be an easy way to obtain non-conjugated fluorescent polymers for photoelectric devices by solution processing. The electroluminescent properties of these polymers were reported briefly in this paper.
