Mellitic triimides (1) undergo three sequential one-electron reduction processes whose potentials are significantly lowered in the presence of alkyl thioureas. Using computational models we can predict the minimum energy binding modes in these systems and calculate the relative free energy changes between the electronic states in both the bound and unbound states.
Phenanthrenequinone undergoes rapid proton transfer processes in the presence of a thiourea substituted random styrene copolymer, while interactions with a similar benzyl-thiourea monomer in different dielectric environments demonstrate strong redox modulation of the quinone without proton transfer.
