  (SEC), a technique that combines IR spectroscopy with electrochemistry. Four different Mn and Re catalysts for electrochemical CO2 reduction were studied in dry acetonitrile. In the case of Mn(apbpy)(CO)3Br (apbpy = 4(4-aminophenyl)-2,2'-bipyridine), SEC suggested that a very slow catalytic reduction of CO2 also occurs in acetonitrile in the absence of proton donors, but at rather negative potentials

  本研究旨在利用红外光谱电化学（SEC）（一种将红外光谱与电化学相结合的技术）来展示不同配合物的行为。研究了四种不同的 Mn 和 Re 催化剂，用于在无水乙腈中进行电化学 CO2 还原。对于 Mn(apbpy)(CO)3Br（apbpy = 4(4-氨基苯基)-2,2'-联吡啶），SEC 表明，在没有质子供体的情况下，乙腈中也会发生非常缓慢的 催化还原，但电位相当负。相比之下，相应的 Re(apbpy)(CO)3Br 在第一次还原电位下明显表现出缓慢的催化转化。改用乙腈和 5% 水的混合物中的饱和 溶液作为质子供体，Mn(apbpy)(CO)3Br 的 SEC 显示出更快的催化行为。

  Here we report an electrochemiluminescence (ECL) self-interference spectroscopy technique (designated as ECLIS) with spatial resolution in the normal direction of the electrode surface. Self-interference principally originates from the superposition of ECL emitted directly by luminophores and that reflected from electrode surfaces, resulting in a spectrum consisting of orderly distributed peaks. On the basis of this spectrum and theoretical analysis by the matrix propagation model, the distance between luminophores and the electrode surface can be probed with a vertical resolution on the nanometer scale. We demonstrated first in this work that the height of ECL luminophores assembled on the electrode surface using different molecular linkers, such as double-stranded DNA, could be determined, as well as the possible conformation of linker molecules at the surface. Moreover, the thickness of the ECL emitting layer adjacent to the electrode surface was estimated for the classical coreactant ECL systems involving freely diffusing Ru(bpy)(3)(2+) and tri-n-propylamine in solutions. The thickness was found to vary from similar to 350 nm to nearly 1 mu m depending on the concentration of Ru(bpy)(3)(2+). We believe that ECLIS with a high vertical resolution will provide an easy way to collect molecular conformation information and study ECL reaction mechanisms at electrode interfaces.
