Metal-organic framework nanoparticles (nanoMOFs) are a new generation of nanomaterials that have a diverse range of applications including catalysis, mixed matrix membranes, and electrochemistry. Key to the utility nanoparticles is their colloidal stability. The Brozek group has discovered that nanoMOFs are often indefinitely stable in solution. Compared to traditional colloids that require the addition of surfactant to the nanoparticle surface to maintain stability, these nanoMOFs are stable as synthesized. Here, we report our investigations into the solvent interactions that give rise to their colloidal stability. Through the combination of calorimetry and SFG-IR, the interaction between solvent and nanoMOF is investigated showing evidence of the solvent structure and binding environment between solvent and nanoMOF.
