Many, if not most, redox reactions are coupled to proton transfers. This includes most
common sources of chemical potential energy, from the bioenergetic processes that power …

At the core of many important energy conversion processes in chemistry and biology are
oxidation-reduction reactions in which both electrons and protons are transferred. An …

Since their discovery in 1985 1 and their production on a preparative scale 5 years later, 2
fullerenes have attracted a great deal of attention. Their chemical modification has emerged …

Electron transfer (ET) reactions are fundamental steps in biological redox processes.
Respiration is a case in point: at least 15 ET reactions are required to take reducing …

Proton-coupled electron transfers (PCETs) are unconventional redox processes in which
both protons and electrons are exchanged, often in a concerted elementary step. While …

Excited-state proton-coupled electron transfer (ES-PCET) is a promising avenue for solar
fuel production and small molecule activation. Although less is known about ES-PCET …

An enormous variety of biological redox reactions are accompanied by changes in proton
content at enzyme active sites, in their associated cofactors, in substrates and/or products …

In order to clarify mechanisms of excited state interactions in hydrogen-bonded pairs, we
have studied the kinetics of dynamic quenching of singlet and triplet fluorenone by a series …

Redox reactions of tyrosine play key roles in many biological processes, including water
oxidation and DNA synthesis. We first review the redox properties of tyrosine (and other …

Studies in proton-coupled electron transfer (PCET) often require the combination of an outer-
sphere oxidant and a base, to remove an electron and a proton. A common problem is the …
