阴离子从水相到有机相的三相边界转移可以用 4-(3-苯基丙基)-吡啶)（或 PPP）中的四苯基卟啉-Mn(III/II)（或 TPPMn）氧化还原系统以电化学方式驱动。研究的阴离子有高氯酸根、氯离子、氟离子和碳酸氢根。与高氯酸盐和氯化物的情况相比，碳酸氢盐和氟化物的转移过程在化学上更加复杂，紫外可见分光电化学测量分别表明 HCO3−/CO32− 转移过程以及氟化物与 TPPMn(III)+ 的结合。原位光谱电化学被开发用于介孔 ITO 导电薄膜电极上亚微升有机相区域的离子转移伏安法。
The triple phase boundary transfer of anions from the aqueous into an organic phase can be driven electrochemically here with the tetraphenylporphyrinato‐Mn(III/II) (or TPPMn) redox system in 4‐(3‐phenylpropyl)‐pyridine) (or PPP). Anions investigated are perchlorate, chloride, fluoride, and bicarbonate. The bicarbonate and fluoride transfer processes are shown to be chemically more complex compared to the perchlorate and chloride cases with UV‐vis‐spectroelectrochemical measurements indicating a combination of HCO3−/CO32−transfer processes and association of fluoride with TPPMn(III)+, respectively. In situ spectroelectrochemistry is developed for ion‐transfer voltammetry into sub‐microliter organic phase regions on mesoporous ITO conducting film electrodes.
