【摘要】：多酸超分子有机-无机杂化化合物已经引起人们的广泛关注，不仅是由于它们结构的多样性和电子的多功能性，还因为它们在催化、药物、分子磁性和材料科学等领域的潜在应用。随着多酸化合物的合成进入分子剪裁和组装时代，，在有机模板剂的调节作用下，一批结构新颖的多酸化合物层出不穷。由于多酸化合物在催化、药物、材料科学方面的潜在应用，人们对多酸化合物功能化的研究日趋重视。 本文合成了杂多酸和甘氨酸的超分子化合物α-K_2(HGly)_3[SiW_(11)Fe(H_2O)O_(39)]·24H_2O和α-K_4(HGly)_3[SiW_(11)Ti(H_2O)O_(39)]·4H_2O，并利用红外光谱、紫外光谱等手段进行了表征，采用TG-DTG技术研究了超分子化合物的非等温动力学。运用Coats-Redfern积分法和Achar微商法对非等温动力学数据进行了分析，得出了热分解反应的机理函数、动力学参数以及3步分解反应的活化能E和lnA。
[Abstract]:Polyacid supramolecular organic-inorganic hybrid compounds have attracted widespread attention, not only because of their structural diversity and the versatility of electrons, but also because of their catalysis, drugs, Potential applications in fields such as molecular magnetism and material science. With the synthesis of polyacid compounds entering the era of molecular tailoring and assembly, a number of novel polyacid compounds emerge in endlessly under the regulation of organic templates. Due to the potential applications of polyacid compounds in catalysis, medicine and material science, more and more attention has been paid to the functionalization of polyacid compounds. The supramolecular compounds 伪 -K _ S _ 2 (HGly) _ 3 [SiW_ (11) Fe (H _ 2O) O _ (39)] 24H_2O and 伪 -K _ 4 (HGly) _ (39) [SiW_ (11) Ti (H _ 2O) O _ (39)] _ 4H _ 2O were synthesized and characterized by IR and UV spectra. The non-isothermal kinetics of the supramolecular compounds was studied by TG-DTG technique. The non-isothermal kinetic data were analyzed by Coats-Redfern integration method and Achar microquotient method. The mechanism function, kinetic parameters and activation energy E and lnA. of the three-step decomposition reaction were obtained.
