Thermogravimetic Study Of Chrysodine Dye Type Bridge Containing Bis (8-quinolinol)s Ligands and Their Coordination Polymers
Abstract: Our thermogravimetric analysis state that the degradation in chrysodine dye type bridge containing bis (8-quinolinol)s metal coordination polymers was initiated at almost the same temperature near about 25-500 C(T0). The remarkable difference is observed in the mode of thermal degradation of the parent ligand and its coordination polymer. The unchelated bis(8-quinolinol) ligand and coordination polymers begin to decompose almost at the same temperature but in the polymer chelates this decomposition …
