Synthesis And Properties Of Metal Coordination Polymers Containing Azobenzene-quinolin Unit

This paper designed and synthesized three novel containing azobenzene-quinoline structure of polyester and6metal coordination polymers containing azobenzene-quinoline structure. By IR, UV-vis, MS and1H NMR monomer,polyester and metal coordination polymers were characterized. As measured by GPC of polyester P1～P3with the metal and a polymer average molecular weight (Mn) was14665g/mol,10892g/mol,13196g/mol; weight average molecular weight (Mw) was27717g/mol,19388g/mol,25466g/mol; molecular weight distribution index (PDI) were1.89,1.78,1.93. TG measured P1and P1-Zn-Q, P1-Al-Q, respectively, the5%weight loss temperature of269℃,279℃and304℃, indicates a metal complex polymer having excellent thermal stability. Azobenzene-quinoline structure of metal coordination polymers can be dissolved in DMF, DMSO, DMAc and NMP, dissolved in CHCl3and THF in part.In the UV spectrum, the metal complex of the polymer of about266nm in both the benzene ring and a quinoline ring (?) of the absorption peak at about442nm,488nm appears at about azobenzene-quinoline structure (?)*peaks. In the fluorescence spectrum, the polyester P1～P3(2.0×10-5mol/L solution in DMF) were purple fluorescence emission450nm,419nm and420nm; metal complex polymer P-Zn-Q respectively559nm,557nm and558nm of the orange yellow phosphor; metal complex polymer P-Al-Q, respectively527nm,548nm and550nm of the yellow-green fluorescence. We synthesized containing azobenzene-polyester P1～P3and metal coordination polymers quinoline structure has good thermal stability, optical properties and solubility, with potential application in the field of optoelectronic functional polymer materials.
