Oxygen carriers based on electrochemically reduced trinitroarenes.
1,3,5-Trinitrobenzene, 2,4,6-trinitrotoluene and 1-methoxy-2,4,6-trinitrobenzene undergoes reversible dimerization, after electrochemical reduction of two units of corresponding anion radical. The pi-dimer formed captures molecular oxygen (O(2)) leading to a sigma(o-o)(H)-adduct, in an atmosphere of oxygen or even air. The sigma(o-o)(H)-adduct is able to reversibly bind and remove dioxygen after an external redox stimulus.
