(A) Steady-state CV of TEA⁺ transfer across the DCE/water interface as obtained using a 19 nm-radius water-filled nanopipet at 10 mV/s. The DCE and water phases contained 1.7 and 2.6 mM TEA⁺ as tetrakis(4-chlorophe- nyl)borate (TPBCl) and chloride salts, respectively. Supporting electrolytes in the respective phases are 9.4 mM tetrahexylammonium TPBCl and 0.1 M LiCl. Adapted with permission from ref. [39]. Copyright 2010 American Chemical Society. (B) Plot of log k⁰ values for TEA⁺ transfer reported in literature versus the year of the publication. This type of plot was reported originally by Kakiuchi and more recently by Samec. See ref. [2].
