the framework, as we observe absorption bands similar to those of the linker cobaloxime (Figure ). Elemental analysis using ICP-OES reveals that there are 2.4 Co/Zr6 node, further supporting successful incorporation of the cobaloxime linker. 1 H-NMR spectroscopy of digested ZrCo-MOF samples shows peaks at chemical shifts matching those of [Co(dcpgH)(dcpgH2)Cl2] thus confirming the structural integrity of the cobaloxime linker in the material (Figure ). The thermogravimetric analysis of ZrCo-MOF shows a loss at ∼250 °C that can be attributed to the dehydroxylation of the Zr6 nodes and a loss above 400 °C of the cobaloxime linker that leads to degradation of the framework to form the metal oxide (Figure ). Taken together, we conclude from these results that we successfully synthesized a Zr-based MOF with cobaloxime linkers, thus creating a solid-state version of our homogeneous molecular photocatalyst.
