【摘要】：多酸超分子有機(jī)-無(wú)機(jī)雜化化合物已經(jīng)引起人們的廣泛關(guān)注，不僅是由于它們結(jié)構(gòu)的多樣性和電子的多功能性，還因?yàn)樗鼈冊(cè)诖呋⑺幬�、分子磁性和材料科學(xué)等領(lǐng)域的潛在應(yīng)用。隨著多酸化合物的合成進(jìn)入分子剪裁和組裝時(shí)代，，在有機(jī)模板劑的調(diào)節(jié)作用下，一批結(jié)構(gòu)新穎的多酸化合物層出不窮。由于多酸化合物在催化、藥物、材料科學(xué)方面的潛在應(yīng)用，人們對(duì)多酸化合物功能化的研究日趨重視。 本文合成了雜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，并利用紅外光譜、紫外光譜等手段進(jìn)行了表征，采用TG-DTG技術(shù)研究了超分子化合物的非等溫動(dòng)力學(xué)。運(yùn)用Coats-Redfern積分法和Achar微商法對(duì)非等溫動(dòng)力學(xué)數(shù)據(jù)進(jìn)行了分析，得出了熱分解反應(yīng)的機(jī)理函數(shù)、動(dòng)力學(xué)參數(shù)以及3步分解反應(yīng)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 偽 -K _ S _ 2 (HGly) _ 3 [SiW_ (11) Fe (H _ 2O) O _ (39)] 24H_2O and 偽 -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.
