Co-ordination polymers of bis(8-hydroxy-5-quinolyl)-methane have been prepared by reacting the ligand with Mn(II), Co(II), Ni(II), Cu(II), and Zn(II), in solution as well as by thermal polymerization. The thermal stability of each polymer in vacuum was studied by thermogravimetric analysis up to 1000°C, and the decomposition temperature was found to be closely related to such periodic properties of
通过使配体与Mn(II),Co(II),Ni(II),Cu(II)和Zn(II)反应制备了双(8-羟基-5-喹啉基)-甲烷的配位聚合物,在溶液中以及通过热聚合。通过高达1000℃的热重分析研究了每种聚合物在真空中的热稳定性,并且发现分解温度与并入聚合物主链中的金属的周期性性质如离子电势和电负性密切相关。根据对8-羟基喹诺酮金属盐的现有数据的评估,结果表明,在空气中而非真空中进行测量会得出有关协调系统热稳定性的错误结论。配位聚合物的红外光谱表明,在1100 cm -1处的吸收带频率区域取决于金属离子的离子电势和其他周期性。红外数据提供了有关CO-金属位点上金属-配体键性质的信息。
