The interface formed between two immiscible electrolyte solutions (ITIES) constitutes a fantastic playground for the investigation of charge (under the form of either ion or electron) transfer processes. We have reviewed here the routes for the modification of such soft interfaces by an accurate electrochemical control. The three main strategies developed in the past four decades include (i) the electrochemically controlled assembly of molecules and nano-objects; (ii) the in-situ electrogeneration of nanomaterials and (iii) the use of ex-situ synthesised membranes. Applications of functionalized ITIES in the fields of redox catalysis and electroanalysis of modified soft interfaces are also discussed.

“…Polymeric layers of 4-(pyrrol-1-yl)phenyloxyacetic acid at the water -DCE interface were synthesized although no ET process was recorded [158] Figure 8A) [159]. These polymers were deposited as result of the oxidation of the corresponding monomer with ferric ions, followed by its oligomerization and subsequently polymerization.…”

“…Owing to a higher oxidation potential, the derivatives with one pyrrole unit in the molecule can be oxidized by a stronger oxidant like the aqueous Ce 4+ cation [11,13]. In contrast, the lower oxidation potential of the derivatives with two pyrrole units in the molecule makes it possible to use a weaker oxidant like the aqueous Fe 3+ cation [12] The use of Fe 3+ is more advantageous, because the solution acidity need not be as high as with Ce 4+ .

Approaches to the formation of a dense and stable surface layer at the polarized liquid/liquid interface affecting the selectivity of the interfacial ion transfer are considered. Three examples of the preparation of such surface layers, including the silicate membrane, the ion-pair stabilized phospholipid film, and a polymer surface layer, are discussed. Relevance of studies in this area to modeling of the biological and technological membrane processes is highlighted.

Porphyrin containing isoindoline nitroxides as potential fluorescence sensors of free radicals

A series of new spin-labeled porphyrin containing isoindoline nitroxide moieties were synthesized and characterized as potential free radical fluorescence sensors. Fluorescence-suppression was observed in the free-base monoradical porphyrins, whilst the free-base biradical porphyrins exhibited highly suppressed fluorescence about three times greater than the monoradical porphyrins. The observed fluorescence-suppression was attributed to enhanced intersystem crossing resulting from electronexchange between the doublet nitroxide and the excited porphyrin fluorophore. Notably, fluorescencesuppression was not as strong in the related metalated porphyrins, possibly due to insufficient spin coupling between the nitroxide and the porphyrin. Continuous wave EPR spectroscopy of the diradical porphyrins in fluid solution suggests that the nitroxyl-nitroxyl interspin distance is long enough and tumbling is fast enough not to detect dipolar coupling.
