• authors pointed out that metal clusters (for example, isoreticular MOFs) essentially define the overall electronic properties of MOFs and provide MOFs with the characteristics of a wide-bandgap semiconductor like ZnO. The size of the organic linker and the hybridization of the central atom of the linker

Due to MOFs’ low resistivity and rapid charge carrier mobility, some researchers [80][81][82][83] have recently

• the linker, not the metal, is often the focal point of luminescence from such MOFs [85]. Because ligand–metal transitions (d→d) may strongly reabsorb or quench the fluorescence produced by the organic linker via energy or electron transfer through the partially filled d orbitals, the emission from

The growth of ZIF-8 membranes under various parameters was evaluated by field-emission scanning electron microscopy, and the

When the organic linker concentration increased from 12.5 to 400 mM, the CO2 permeance first decreased and then increased (Table 2

The 2-methylimidazole concentration was then sufficient to react with the Zn ions, but not too high to cause an overly high diffusion rate and the consumption of all Zn ions at the initial

• elimination of some organic fragments from the organic linkers. The last weight loss from 300 to ca. 870 °C is largely due to the oxidative elimination of the organic linker [47] and further condensation of the silanol groups. The remaining weight at 900 °C is due to silica and carbon residues. Figure 5 shows

• remaining silanol groups, or to traces of organic solvent from the synthesis. Between 260 and 420 °C a significant mass loss of ca. 70% is observed. It is mainly due to the decomposition of the IL but the decomposition of the organic linker in the organosilica matrix also contributes to this weight loss
