Cyclic voltammetric and spectroelectrochemical evidence is presented showing that the H-bonded dimer formed from a ureidopyrimidone derivative containing a phenylenediamine redox couple can be reversibly broken apart at mM concentrations in CH2Cl2 by

It is well-established that very weak acids such as water and alcohols strongly H-bond to quinone dianions, Q2–, in aprotic solvents. This results in thermodynamic stabilization of Q2– and a shift of the formal potential of the Q–/2– couple t

The kinetics of many proton-coupled electron transfer (PCET) reactions cannot be adequately described by step-wise proton and electron transfer. Concerted electron-proton transfer (CPET) is another possibility, but examples exist where step-wise mech

Ureidopyrimidinone (UPy) derivatives, introduced by Meijer and co-workers, are capable of forming dimers linked by four strong H-bonds. They have been widely used as polymer crosslinkers in self-healing supramolecular polymers and gels. While their d

Strength and directionality are the hallmark characteristics of binding for molecules with multiple hydrogen bonds. This is important in the area of molecular recognition and supramolecular construction. When coupled to a redox center, oxidation or r

An important class of supramolecular systems are those capable of forming dimers held together by multiple linear H-bonds. Of these, the 4 H-bond arrays based on the ureidopyrimidone or UPy unit have found particularly use, having the right combinati

Proton transfer often accompanies electron transfer in organic redox couples due to the large changes in acidity or basicity that result from oxidation or reduction. Classically, the overall reaction is thought to occur in two separate steps, either

Oxidation or reduction of organic redox couples typically leads to large changes in acidity or basicity, with the result that proton transfer often accompanies electron transfer, particularly in aqueous solution. In less polar organic solvents, H-bon

The voltammetry of 2,3,5,6-tetramethyl-p-phenylenediamine, H2PD, has been studied and compared to that of its isomer N,N,N’N’-tetramethyl-p-phenylenediamine, Me2PD. Both undergo two reversible electron transfer processes in acetonitrile that nomi
