Using synchrotron-based FTIR spectroscopy in specular reflectance, in conjunction with density functional theory (DFT) calculations, we have revealed detailed structure-property trends linking the THz region dielectric response to framework porosity and structural density. The work demonstrates that MOFs are promising candidate materials not only for low-\\k{appa} electronics applicatio","authors_text":"Bartolomeo Civalleri, Chris S. Kelley, E.M.
