“…5 , the energy of 1-1D is higher than that of 1-0D by 0.04 eV per [Zn II (eg) 3 ]SO 4 molecule. Such a small energy change, which is smaller than the energy variations for typical solid-state phase transitions 10 – 12 , 43 , 44 , can be compensated by the entropy gain associated with the release of eg molecules during the transition. According to the calculation, the most energy-consuming step is 1-0D → INT1 (1.02 eV uphill), where one Zn−O(eg) coordination bond is substituted by a sulfate ion.…”

Numerous single crystals that exhibit single-crystal-to-single-crystal (SCSC) transformations have been reported, and some of them show great promise for application to advanced adsorption materials, magnetic switches, and smart actuators. However, the development of single crystals with super-adaptive crystal lattices capable of huge and reversible structural change remains a great challenge. In this study, we report a ZnII complex that undergoes giant SCSC transformation induced by a two-step thermal elimination of ethylene glycol chelating ligands. Although the structural change is exceptionally large (50% volume shrinkage and 36% weight loss), the single-crystal nature of the complex persists because of the multiple strong hydrogen bonds between the constituent molecules. This allows the reversible zero-dimensional to one-dimension and further to three-dimensional structural changes to be fully characterized by single-crystal X-ray diffraction analyses. The elimination of chelating ligands induces a chiral interconversion in the molecules that manifests as a centric-chiral-polar symmetric variation of the single crystal. The study not only presents a unique material, featuring both a periodic crystal lattice and gel-like super-ductility, but also reveals a possible solid-state reaction method for preparing chiral compounds via the elimination of chelating ligands.

“…Recently our groups reported an ultrafast lattice rearrangement upon solvent desorption in Al-MOFs. 28 This unique rearrangement allows for an internal self-perfection, leading to a remarkable increase in surface area from 725 to 2,749 m 2 g À1 . Following the encapsulation-rearrangement strategy, we designed a selective external covalent modification based on the internal lattice rearrangement of aluminum-based mesoporous MOFs.…”

A metal-organic framework (MOF) material was integrated with surface superhydrophobicity, high surface areas, large and uniform pore sizes, and excellent stability. This synthetic procedure was completed via an encapsulationrearrangement strategy. Benefiting from the superhydrophobicity, this MOF could be stable in humid environments and maintained its mesoporosity and surface areas for at least 6 months. The MOF-modified sponge has great potential in applications such as oil/water separation, water remediation, and heterogeneous catalysis.

View full text Add to dashboard Cite

Two‐dimensional conductive metal–organic frameworks (2D c‐MOFs) as an emerging class of multifunctional materials have attracted extensive attention due to their predictable and diverse structures, intrinsic permanent porosity, high charge mobility, and excellent electrical conductivity. Such unique characteristics render them as a promising new platform for electrical related devices. This Minireview highlights the recent key progress of 2D c‐MOFs with emphasis on the design strategies, unique electrical properties, and potential applications in electrochemical energy storage. The thorough elucidation of structure–function correlations may offer a guidance for the development of 2D c‐MOFs based next‐generation energy storage devices.
