The Research On Design And Application Of Nonlinear Chemical System Catalyzed By A Macrocyclic Complex

In recent 30 years, the emergence of multiple steady state, chemical chaos, Turing pattern, chemical wave and chemical oscillation of nonlinear chemical phenomena under the condition of far from equilibrium has caused the scientific workers attention. These self-organization phenomena can be seen everywhere in the nature. According to the dissipative structure theory, the specific chemical self-organization system can evolve into spatiotemporal in certain conditions, such as chemical oscillation, chemical wave as well as the pattern formation.In this paper,there are two kinds of new chemical oscillator:BR chemical oscillator (KIO3-[NiL](ClO4)2-malonic acid-H2SO4-H2O2) and B-Z chemical oscillator (bromate-1,4-Cyclohexadione-[CuL](ClO4)2-H2SO4. We evaluate antioxidant capacity study spatiotemporal patterns by new chemical oscillator. The characteristic of the new chemical oscillator is catalyst tetraaza-macrocyclic diene nickel complex and tetraaza-macrocyclic diene copper complex. The catalyst with the porphyrin ring enzymes is similar to enzymes which has great significance on biochemical oscillations simulation research.The first introduction part mainly introduced several kinds of nonlinear chemical phenomenon about its research history, the reaction conditions, development situation of the application and the mechanism.The second part we mainly study effect of ferulic acid on new BR oscillation system. The unique structure of tetraaza-macrocyclic diene nickel has great significance on biochemical oscillations simulation research. The [NiL](ClO4)2-catalyzed oscillating system has several advantages than other oscillating system such as higher sensitivity, higher selectivity and wider detection range. Detection range of ferulic acid can even reach 10-8 mol/L. At the same time, we analyze the influence factors of disturbance behavior to get a best condition to test the ferulic acid.We summarized the mechanism by analyzing cyclic voltammograms according to the predecessors’ experience.The third part we mainly study effect of the sesamol on new BR oscillation system (KIO3-[NiL](ClO4)2-malonic acid-H2SO4-H2O2. Sesamol proves to be excellent nontoxic antioxidant compared to the traditional antioxidants. We use platinum electrode and reference electrode to monitor potential changes of BR oscillation system with time. It is found that with the increase the concentration of sesamol, the inhibition and the induction period of the oscillation system change obviously. In a certain concentration range, we found linear relationship between concentration of sesamol and inhibition time At. At the same time, we analyze the influence factors of BR oscillation system which are the substrate malonic acid, potassium iodate, hydrogen peroxide, the catalyst to explore the relationship between the inhibition of time and each component content in the oscillation system.In the end,we get a to get a best conditions to test the sesamol. We summarized the mechanism by analyzing cyclic voltammograms according to the predecessors’ experience.The fourth part we study the new B-Z oscillating system in which a macrocyclic complex was used as a catalystThe fourth part we study the new B-Z oscillating system in which a macrocyclic complex was used as a catalyst (bromated-1,4-Cyclohexadione-[CuL](ClO4)2-H2SO4). We use diphenylamine (DPA) as an indicator to study the chemical waves, in a closed environment. The new B-Z oscillating system of bromated-1,4-Cyclohexadione-[CuL](ClO4)2-H2SO4 is one of the most suitable research model of nonlinear phenomena which can produce long periodic oscillation and form chemical waves. This system is sensitive to the light and can produce no gas or precipitation. That can make great significance on studying the new spatiotemporal pattern. We also have tried to explain mechanism of new B-Z oscillating system.
