Polarizable Continuum

The energetics of the two main proton coupled electron transfer processes that could occur in DNA are determined by means of time dependent-DFT calculations, using the M052X functional and the polarizable continuum model to include solvent effect.

Physical And Chemical

<p>Simple ionic liquids exhibit unique physical and chemical<br />properties that make them very useful for deployment in electrochemical<br />devices such as solvent-free electrolytes in capacitors and batteries.<br />However, incorporating redox functionality into ionic liquid<br />structures opens up in situ faradaic electrochemistry which allows access<br />to a large array of new electrochemical applications reliant upon<br />heterogeneous or homogenous electron-transfer processes. This paper<br />presents and discusses the opportunities and challenges for these types<br />of electro-materials across a myriad of applications by considering<br />exemplar quinone-functionalised ionic liquids.</p>

An overview of the metal-mediated synthesis and use of nanosized metallodendrimers is given with emphasis on electron-transfer processes (molecular batteries consisting in dendrimers decorated with a large number of equivalent redox-active centers) and catalytic reactions (electron-transfer-chain catalytic synthesis of dendrimers decorated with ruthenium carbonyl clusters, redox catalysis of nitrate and nitrite electroreduction in water by star-shape hexanuclear catalysts).

We describe the design and synthesis of ferrocene dimers and trimers bridged by an oligothiophene spacer as both cathodic and anodic multiple redox-active organic–organometallic hybrid molecules. The electrochemical properties of all compounds were examined by cyclic voltammetry (CV). The voltammograms showed different multi-step, multi-electron redox reactions derived from multi-ferrocene fragments and the organic spacer. The results indicate that a number of thiophene rings in the spacer can be attuned to the redox potentials and the electron-transfer processes.
