Electrochemistry, supramolecular

The electrochemical properties of redox-active substrates are also affected on binding to a receptor molecule. This is the case for the complexation of metal hexacyanides by polyammonium macrocycles where the shift of the redox potential depends on the binding constants and the oxidation or reduction of the substrates leads to pronounced changes in stability (see Chapter 3) [3.21, 3.22]. 

Systems presenting many identical redox-active components bound to a central core or assembled by specific interactions represent approaches towards molecular batteries, i.e., molecular devices capable of performing the reversible exchange (storage and release) of many electrons at the same potential.

The term modified electrodes encompasses a broad variety of electrode materials obtained by attaching a monomolecular layer of a specific compound on the surface of a conducting solid [338]. In electrocatalysis, modified electrodes are common in the field of oxygen reduction, where carbon materials can be modified for example by attaching layers of macrocycles. Modified electrodes are very common in the field of molecular or supramolecular electrochemistry, especially in the organic area.

Recently, the Kaifer group, whose work combines supramolecular electrochemistry with solid spectroscopic characterization of their systems, studied the interaction of cucurbit[7]uril (CB7, 37) with ferrocene-containing dendrimers up to three generations (FGl (38), FG2 (39), and FG3 (40) see Fig. 6.18). They found, inter alia, that, at pH 7, the diffusion coefficients of the functionalized dendrimers are smaller than the corresponding diffusion coefficients measured at pH 2 which, according to the authors, should be attributed to the fact that, under acidic condi-...

The work summarized in this article relates to some of the most exciting areas of supramolecular chemistry. The interdependence of electron-transfer reactions with supramolecular interactions is at the core of the development of switchable molecular devices. Furthermore, research in areas of supramolecular electrochemistry may open the way for technological applications such as responsive (intelligent) materials. A possible impact in the field of electrochemical sensors is also readily visualized from the work described here.

Construction of Nanoplatforms and Supramolecular Electrochemistry from Functional Electrodes... 

Supramolecular electrochemistry of functional nanoplatforms is a new multidisciplinary approach for nanoscience and nanotechnology devoted to investigate electrochemical phenomena by the combinations (or electrodes manipulation) and observation of direct electrochemical analysis of nanomaterial. This combination allows studying complex entities of interest for sensor and biosensor applications.
