Electrochemical In Situ/operando Spectroscopy and Microscopy Part 1: Fundamentals

Electrochemistry, 2022
Spectroscopic and microscopic techniques are complementary to electrochemical studies because electrochemical data consists of current, voltage and time, and has no direct information concerning the chemical structure of active species.

Electrochemical and Spectroelectrochemical Study of N-hydroxyphthalimide at Poly(4-vinylpyridine) Coated Electrodes

Electrochemistry
Electrodes coated with poly(4-vinylpyridine) (PVP) shift the oxidation peak potential of N-hydroxyphthalimide (NHPI) in acetonitrile to a less positive direction compared with that at the uncoated electrodes, which promotes proton-coupled electron ...

Single-Electron Redox Chemistry on the [Cp*Rh] Platform Enabled by a Nitrated Bipyridyl Ligand

Molecules, 2018
[Cp*Rh] complexes (Cp* = pentamethylcyclopentadienyl) are attracting renewed interest in coordination chemistry and catalysis, but these useful compounds often undergo net two-electron redox cycling that precludes observation of individual one-electron ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...
