We combine experiments and simulations to study the adsorption of water in several UiO-66 frameworks (ideal defect-containing structures). propose a new set charges for that accurately provides water-structure interaction at molecular level. The is suitable predicting ideal structure, providing first time, good agreement between experimental calculated isotherms. proposed procedure tuning point framework achieve with universal can easily be extended other MOFs. explore structural...
Intentionally introduced defects into solid materials create opportunities to control and tune their diverse physicochemical properties. Despite the growing interest in defect-engineered metal-organic frameworks (MOFs), there are still only a handful of studies on defective proton-conducting MOFs, including no reports two-dimensional ones. Ion-conducting fundamentally great importance development energy storage conversion devices, fuel cells batteries. In this work, we demonstrate...
Four new layered flexible metal-organic frameworks (MOFs) containing a diacylhydrazone moiety, namely, guest-filled [Zn2(iso)2(tdih)2]n (1), [Zn2(NH2iso)2(tdih)2]n (2), [Cd2(iso)2(tdih)2]n (3) and [Cd2(NH2iso)2(tdih)2]n (4) were synthesized using terephthalaldehyde di-isonicotinoylhydrazone (tdih) as linear ditopic linker well isophtalate (iso) or 5-aminoisophthalate (NH2iso) angular colinkers. The MOFs with hexacoordinated cadmium centers feature two-dimensional pore systems compared to the...
By using the strategy of pre-assembly chlorosulfonation applied to a linker precursor, first sulfonated zirconium metal-organic framework (JUK-14) with two-dimensional (2D) structure, was synthesized. Single-crystal X-ray diffraction reveals that material is built Zr6 O4 (OH)4 (COO)8 oxoclusters, doubly 4-connected by angular dicarboxylates, and stacked in layers spaced 1.5 nm apart presence sulfonic groups. JUK-14 exhibits excellent hydrothermal stability, permanent porosity confirmed gas...
Rational design of organic building blocks provides opportunities to control and tune various physicochemical properties metal–organic frameworks (MOFs), including gas handling, proton conduction, structural flexibility, the latter which is responsible for new adsorption phenomena often superior compared rigid porous materials. In this work, we report synthesis, crystal structures, adsorption, conduction a flexible two-dimensional cadmium-based MOF (JUK-13-SO3H-SO2) containing sulfonated...
A 20-Å-long diacylhydrazone linker was used for the first time as a building block construction of metal–organic framework (MOF). The terephthalaldehyde di-isonicotinoylhydrazone (tdih) is considerably longer than its 11-Å-long monoacylhydrazone counterpart, 4-pyridinecarboxaldehyde isonicotinoylhydrazone (pcih), so far MOF linker. By utilizing two ditopic hydrazone linkers providing linear connectivity, nonisoreticular cadmium–organic frameworks, {[Cd2(oba)2(hydrazone)2]}n (with oba =...
In this work, density functional theory (DFT) and Monte Carlo calculations were combined with standard volumetric adsorption as well quasi-equilibrated temperature-programmed desorption measurements to study water in UiO-66 derivatives containing −NH2, −NO2, −Br substituents. Based on DFT modeling, both the position geometry of substituents determined one model was selected for each structure. By using simulations force field developed our previous work metal–organic frameworks, we...
Terminal sulfonic acid groups characterize various proton conducting materials including metal-organic frameworks (MOFs). These groups, however, show strong coordination ability that hinders their direct intact incorporation. We present a strategy for introducing pendant SO3H into from sulfonyl chloride precursors. The using concerted deprotonation-metalation-hydrolysis reaction yields new MOF capable of transport.
A solid-contact ion-selective electrode was developed for detecting potassium in environmental water. Two versions of a stable cadmium acylhydrazone-based metal organic framework, i.e., JUK-13 and JUK-13_H2O, were used the construction mediation layer. The potentiometric electrochemical characterizations proposed electrodes carried out. implementation JUK-13_H2O interlayer is shown to improve response stability measured potential. exhibits good Nernstian slope (56.30 mV/decade) concentration...
Dynamic multicomponent metal-organic frameworks, comprising numerous functional groups attached to a flexible backbone, expedite the complexity of coordination chemistry. Both factors, stimuli-responsiveness, and non-homogeneous environ-ments, are pivotal for creating complex systems that bring scientists closer understanding biological structures, nevertheless, com-prehension such remains largely unexplored. Inspired by this concept, we prepared series multivariate JUK-8(NO2)x(Br)1-x (0...
