The photoresponsive MOF Zn(AzDC)(4,4'-BPE)0.5 was chosen based on previous reports that it exhibits a decrease in gas uptake when exposed to UV light: a difference of 64% was found under dynamic conditions and 42% under static conditions. In addition, this material was noted for having selective adsorption for carbon dioxide over methane. In our hands, the CO2 uptake of this MOF varied considerably between batches, ranging from 277-766 µmol/g at 1 bar / 301 K, even when the synthesis and activation was carried out on the same scale (Figure ), though there was little variation in the measured particle size distributions of the three batches selected for further analysis (Figure , Table ). It is therefore possible that the variation in CO2 uptake is due to the formation of differing quantities of triply, double, and nonpenetrating frameworks, where differences can be seen in the PXRD patterns which deviate from the reported triply-interpenetrated framework (Figure ). For the batch with the largest CO2 uptake, a reduction in CO2 uptake of 31% was achieved under static irradiation conditions at 365 nm with 100% exposure in the 3D printed reactor (CO2 uptake, 1 bar: 766 µmol/g, ambient; 526 µmol/g under UV irradiation). Next, a suitable solvent was selected to produce a Type III porous liquid. To date, a wide variety of liquids have been used, including organic solvents, oils, and ionic liquids. For this study, we screened a small number of liquids that have previously been reported as being size-excluded for POCs and MOFs, including silicone oil AR 20, and the ionic liquids ). Ionic liquids are good candidates for porous liquids due to their low vapour pressures, compatibility with organic and inorganic materials, and their ability to be tailored to suit different applications. To screen these solvents for sizeexclusion from the MOF, 12.5 wt. % dispersions were prepared, and the CO2 uptake was measured under ambient conditions (i.e., with no exposure to UV or blue light) while stirring at 300 rpm (Figure ). While several of these combinations showed enhanced CO2 uptake compared to the neat liquids, which indicated the successful formation of Type III porous liquids, silicone oil AR 20 and [BMIM][NTf2] demonstrated the highest CO2 uptakes when compared to the neat liquids.
