Understanding Cu(i) local environments in MOFs via^63/65Cu NMR spectroscopy

Abstract

The field of metal-organic frameworks (MOFs) includes a vast number of hybrid organic and inorganic porous materials with wide-ranging applications. In particular, the Cu(I) ion exhibits rich coordination chemistry in...

Influence of Ge substitution on the structure and optical properties of Cu2ZnSn1−xGexS4 photovoltaic materials

“…To evaluate these models, 63/65 Cu NMR spectroscopy is a useful technique applied successfully to similar problems in other compounds. 25–27,48–50 For Cu 2 ZnGeS 4 , the two Cu sites in model A are surrounded by the same types of atoms in the second coordination sphere, Cu@[Cu 4 Zn 4 Ge 4 ], but in different arrangements (Fig. 3a).…”

A focus on applying 63/65Cu solid-state NMR spectroscopy to characterize Cu MOFs

“…Moreover, other spectroscopic techniques, such as powder X-ray diffraction, energy dispersive spectroscopy (EDS), etc., oen do not yield high-resolution information on local structural details of the metal centers. Hence, Zhang et al have exploited 63/65 Cu solid-state nuclear magnetic resonance (NMR) spectroscopy, a powerful method of choice to extract site-specic information of these copper environments in MOFs [(https://doi.org/ 10.1039/D4SC00782D) 5 and ref . 6].…”
