摘要
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） reaction catalyzed by tris（2,2′-bipyridine）ruthenium（Ⅱ）,one of the ideal chemical reaction system for studying nonlinear spatiotemporal dynamics,has unique photosensitive properties and can display rich spatiotemporal dynamical behaviors.Achievements of the photosensitive BZ reaction could help us to understand the complex dynamic phenomenon in physical,chemical and living systems.In this paper,the photo-effect on homogenous complex dynamics and reaction-diffusion chemical waves in ruthenium-catalyzed BZ reaction under different experiment conditions,as well as the complex dynamics in coupling system of the ruthenium-catalyzed BZ reaction with soft matter is reviewed.The photosensitive mechanisms and models are summarized.Finally,the existing questions and future directions of the research of photo-controlled BZ reaction systems are discussed.
