玫瑰精 B 能从 Ce 4+-catalyzed Belousov-Zhabotinsky 反应导致震荡的化合光(OCL ) ,这被发现。这个新 OCL 系统,即,玫瑰精 B-malonic acid-bromate-Ce (IV ) 硫磺的酸,在每个摆动时期展出了二座清楚地著名的排放山峰。反应物的起始的集中强烈影响了摆动模式。为 CL 机制的学习,为一个万用、同时的潜力和 CL 测量的一个平台被建立把潜在的摆动与这个系统的 CL 摆动行为作比较。CL 系列,紫外可见的吸收系列和这个 OCL 系统的解决时间的荧光系列被学习。为 OCL 的可能的、简化机制被建议。二座 CL 山峰的产生分别地由于由 Ce (IV ) 和 Br 2, 的玫瑰精 B 的中介的氧化是可能的,这被建议。这个工作提供了一个新方法和平台研究复杂化学摆动。
It was found that rhodamine B could induce oscillating chemiluminescence (OCL) from the Ce4+-catalyzed Belousov-Zhabotinsky reaction. This new OCL system, i.e., rhodamine B-malonic acid-bromate- Ce(IV)-sulfuric acid, exhibited two clearly distinguished emission peaks in each oscillation period. The initial concentrations of the reactants strongly influenced the oscillation pattern. For the study of the CL mechanism, a platform for a versatile and simultaneous potential and CL measurement was estab- lished to compare the potential oscillation with the CL oscillation behavior of this system. The CL spectra, UV-visible absorption spectra and time-resolved fluorescence spectra of this OCL system were studied. A possible, simplified mechanism for the OCL is proposed. It is suggested that the generation of the two CL peaks is likely due to the oxidation of the intermediate of rhodamine B by Ce(IV) and Br2, respectively. This work provided a new method and platform to research the complex chemical oscilla- tions.
