Synthetic Studies on organic Reagents with Specific fluorescence and Their Application to Kinetic Analysis

通过对金属配合物与香豆素、色酮或黄酮作为荧光配体反应的热力学和动力学研究，得到了以下结果，为灵敏和选择性地确定其种类提供了依据：通过对3-羟基黄酮及其钨（VI）、钼（VI）配合物与环糊精包合反应的荧光学研究，获得了荧光增强反应的热力学和动力学的详细图像。从高碘酸盐氧化双胍反应的动力学研究中，定量地解释了金属离子的加速作用。根据催化效果的差异，提出了2 ~ 60 ppb范围内的动力学测定方法。从锑（III）和(V)与铬和黄酮络合反应的热力学研究出发，提出了同时测定锑（III）和(V)的分光光度法，误差约为1g。从金属离子及其配合物反应性的机理出发，估计了金属离子和配体的参数特征。利用这些参数，提出了设计一种新的基于配体取代反应的动力学催化分析的可能性。

From the theromdynamic and the kinetic studies on the reactions involving a metal complex with coumarines, chromones or flavones as a fluorescence ligand, the following results which provide a basis for the sensitive and the selective determination of the species are obtained:1.From the fluorimetric studies on the inclusion reactions of 3-hyroxyflavones and their tungsten(VI) and molybdenum(VI) complexes into cyclodextrine, a detailed picture of the thermodynamics and the kinetics of the fluorescence enhancement reaction has been obtained.2. From the kinetic studies on the oxidation reaction of coumarines by periodate, the acceleration effect of a metal ion was quantitatively accounted for. Based on the difference in the catalytic effect, a kinetic mothod for the determination in the range of 2-60 ppb has been proposed.3. From the thermodynamic studies on the complexation reactions of antimony(III) and (V) with chromones and flavones, a spectrophotmetric method for the simultaneous determination of antimony(III) and (V) with an error about 1 g has been proposed.4. From a mechanistic consideration on the reactivity of a metal ion and its complex, the perameters characteristic of a metal ion and a ligand have been estimated. With these parameters, some possibilities to design a new kinetic-catalytic of analysis based on ligand substitution reactions have been proposed.
