用激光捕集-电化学-光谱法研究了分散在水中的磷酸三丁酯（直径约为20 μm）微滴中二茂铁（FeCp）的电化学行为。直接测量和分析了FeCp和二茂铁离子（FeCp +）在液滴-水界面上的传质，并伴随着FeCp在液滴中的电解。根据FeCp在界面上的分布再平衡对结果进行了讨论，这在光谱上得到了液滴中FeCp对9，10-二苯基蒽的荧光猝灭的支持
Electrochemical behavior of ferrocene (FeCp) in a single tri-n-butyl phosphate microdroplet (diameter= ∼20 μm) dispersed in water was studied by a new method of laser trapping-electrochemistry-spectroscopy. Mass transfer of FeCp and ferrocenium ion (FeCp + ) across the droplet-water interface accompanied by electrolysis of FeCp in the droplet was directly measured and analyzed. The results were discussed in terms of a distribution reequilibrium of FeCp across the interface, which was spectroscopically supported by fluorescence quenching of 9,10-diphenylanthracene by FeCp in the droplet
