“…We hypothesized that cyclopentane, which is immiscible with acetonitrile (Figure c), might extract progesterone from acetonitrile following its light-driven release from cage 1 . Cyclopentane is an attractive extractant due to its low boiling point and heat of evaporation, which minimize energy consumption during solvent recycling . Progesterone⊂ trans - 1 was added to a 1:1 cyclopentane:acetonitrile biphasic system.…”

The 1 H NMR spectrum of the cyclopentane phase indicated no progesterone release prior to illumination.…”

Chemical separations are expensive, consuming 10−15% of humanity's global energy budget. Many current separation methods employ thermal energy for distillation, often through the combustion of carbon-containing fuels, or extractions and crystallizations from organic solvents, which must then be discarded or redistilled, with a substantial energetic cost. The direct use of renewable energy sources, such as light, could enable the development of novel separations processes, as is required for the transition away from fossil fuel use. Metal−organic capsules, which can selectively bind molecules from mixtures, can provide the foundation for these novel separations processes. Here we report a tetrahedral metal−organic capsule bearing light-responsive diazo moieties around its metal-ion vertices. This capsule can be used to selectively separate progesterone from a mixture of steroids in a process driven by visible light energy. Our process combines biphasic extraction and selective binding of progesterone with the light-driven release of this molecule in purified form. Ultimately, our process might be adapted to the purifications of the many other fine chemical products that are bound selectively by capsules.
