Electron transfer

Electron transfer is a process by which an electron moves from one atom or molecule to another. It is a key concept in redox chemistry – the chemistry of reactions where one reaction partner loses electrons (oxidation) while the other gains electrons (reduction).

    Understanding the energetic driving force is important for optimizing the performance of organic solar cells. Here Nakano et al. suggest that the dominant driving force is the energy difference between the singlet excited state and the charge transfer state after assessing 16 material combinations.

    Catalytic oxygen reduction is an important process for clean energy production. Here the catalytic activity of trioxotriangulenes for the oxygen reduction reaction is shown to be correlated with their redox potential, offering a potential route to rationally tune their catalytic activity.

    To demonstrate charge transfer in different Marcus regimes in an organic semiconductor, precise tuning of the material’s electronic properties is required. Here, the authors use a three-terminal hot-electron technique to access the Marcus regimes for electronic transport in organic thin films.

    The donor–acceptor (D-A) conjugation has been adopted for two-dimensional (2D) covalent organic frameworks (COFs) for efficient generation of free charge carriers. Here, the authors investigate the dynamics of photogenerated charge carriers in 2D D-A COFs by combining femtosecond optical spectroscopy and non-adiabatic molecular dynamics simulation.

    Thermal electron transfer across hydrogen bond remains largely unexplored. Here the authors demonstrate that electron self-exchange through hydrogen bonds is highly efficient and can proceed either via the known proton-coupled pathway or an overlooked proton-uncoupled pathway

    Chiral molecules can filter electrons according to their spin. This chiral-induced spin selectivity (CISS) effect can have important applications, such as in spintronics and in enantioseparation. This Review describes the CISS effect, its mechanism and its fascinating applications.

    Certain frustrated Lewis pairs can undergo single electron transfer to give frustrated radical pairs. Such radical pairs have been implicated as important species in the activation of small molecules such as dihydrogen.

    How the first metabolic network was organized to power a cell remains an enigma. Now, simple iron–sulfur peptides have been used to generate a pH-gradient across a protocell membrane by catalysing hydrogen peroxide reduction. This indicates that short peptides could have fulfilled the role of redox active metalloproteins in early life.

    Helium, the 'most noble' of the noble gases, had only been coaxed into forming molecular ions or van der Waals compounds. It has now been seen in a stable solid compound, Na2He, under high pressure.

    Charge transfer through DNA has been well studied over recent decades from both a biological and electronics perspective. It has now been shown that charge transfer can be accelerated one hundredfold by using highly energetic 'hot holes', revealing a new mechanism that could help to create useful electronic biomaterials.

    Electron transfer is ubiquitous across both life and modern technologies, and thus being able to control it is an attractive goal. Now, targeted infrared excitation has been used to modulate the efficiency of electron transfer in a series of donor–bridge–acceptor molecules.
