作为研究非线性时空动力学最理想的化学反应体系之一,三联(2,2’-联吡啶)钌(Ⅱ)(Ru(bpy)32+)为催化剂的Belousov-Zhabotinsky(BZ)振荡反应具有独特的光敏特性并能呈现丰富的时空动力学行为。研究光控BZ反应有助于我们对一系列物理、化学和生命体系中复杂动力学现象的理解。本文综述了不同实验条件下光效应对钌催化BZ反应均相复杂振荡和空间反应扩散化学波的影响,以及光响应BZ反应与软物质耦合体系的复杂动力学行为,在此基础上介绍光抑制和光诱导反应机理和模型。对光控BZ反应体系存在的问题和发展方向进行了探讨。
The Belousov-Zhabotinsky (BZ) oscillatory reaction of Ru (bpy) 32+ (Ru (bpy) 32) as catalyst is one of the most ideal chemical reaction systems for the study of nonlinear spatiotemporal dynamics. Unique photo-sensitive properties and can exhibit rich spatio-temporal kinetic behavior. The study of light-controlled BZ reactions helps us to understand the complex kinetic phenomena in a wide range of physical, chemical and life systems. In this paper, the effects of light effects on the homogeneous and complex chemical reactions of ruthenium-catalyzed BZ reactions and the complex kinetics of light-induced BZ reactions and soft matter-coupled systems under different experimental conditions are reviewed. On the basis of this, And light-induced reaction mechanism and model. The problems and development directions of light-controlled BZ reaction system were discussed.
