Our hypothesis is that a small modular system could be engineered using solvent-based capture and pressure or thermal release of oxygen, to enable oxygen on demand for any combustion-related technology. Task-specific ionic liquid (TSIL)-TEMPO is selected as our base compound for screening selective oxygen generation process and has an unpaired electron, we anticipate a formation of weak complex enabling this fluid to be thermally reversible. TSIL-TEMPO can possibly have high gravimetric capacities of O2, via the diamagnetic supramolecular complex A (2:1 TSIL-TEMPO:O2) or the monodentate complex B (1:1).
