The solubilities of several cobalt(III) chelates (CoL3) with in supercritical carbon dioxide (SC-CO2) were investigated in the presence of fluorine- and trifluoromethyl-substituted phenols (PhOH) using UV-vis spectrophotometry. Solubility enhancement of CoL3 complexes in SC-CO2 was accomplished by adding PhOH. The
