Synthesis and Characterization of Poly(1-methoxy-4-octyloxy)-para-phenylene vinylen for Light-emitting diodes application
In this study,the conjugated polymer,poly(1-methoxy-4-octyloxy)-para-phenylene vinylene (MO-p-PPV)was synthesized and characterized.MO-p-PPV was synthesized according to Gilch polymerization mechanism by using 4-methoxyphenol as starting material in the presence of potassium tert-butoxide (1M in THF).The product was further purified by multiple precipitations in different solvents such as methanol,tetrahydrofuran,isopropyl alcohol and hexane.The final product was dried to afford MO-p-PPV as a red solid.The resulting polymer was completely soluble in common organic solvents.The structure of monomer and optical properties of polymer were characterized by proton nuclear magnetic resonance (1H-NMR) spectroscopy,UV-vis spectroscopy,and fluorescence spectroscopy.The UV-vis spectrum showed absorption maxima for MO-p-PPV at 491nm.Similarly,fluorescence spectrum showed λmax emission at 540 nm.
