Fig. 2: Structural properties of hetero-ligand zirconium-based metal-organic framework (MOF) nanocrystals.

From: Highly luminescent scintillating hetero-ligand MOF nanocrystals with engineered Stokes shift for photonic applications

Fig. 2

a Scanning electron microscopy image of MOF nanocrystals realized with a content of molar DPT fraction of 8% (Zr-DPT:DPA-8%). The inset reports the distribution of MOF size (Scale bar: 200 nm). b N2 adsorption isotherm collected at 77 K. The inset showed the pore size distribution with two distinct cavities of 10.8 Å and 14.5 Å. c Crystal structure of Zr-DPT:DPA highlighting the tetrahedral and octahedral cavities (yellow spheres). d Hyperpolarized laser-assisted 129Xe NMR spectra of hetero-ligand nanocrystals compared with homo-ligand MOFs based on DPA and DPT. The spectra are fitted with a Lorentzian line-shape function (colored areas) for quantitative analysis.
