Metal-organic framework (MOF) materials have emerged as one of the favorite crystalline porous (CPM) because their compositional and geometric tunability many possible applications. In efforts to develop better MOFs for gas storage separation, a number strategies including creation open metal sites implantation Lewis base been used tune host-guest interactions. addition these chemical factors, features such pore size shape, surface area, volume also play important roles in sorption...
A new redox-responsive hybrid nanogated ensemble has been developed by introducing the disulfide-linked polymeric network at outlet of mesoporous silica. The cross-linked polymer works as gatekeeper to control molecule release from presence disulfide reducing agent can effectively open and loading in a tunable manner.
A new pH-responsive hybrid nanogated ensemble has been developed by using acetal group linked gold nanoparticle capped mesoporous silica. The hydrolysis of linker at acidic environment makes the nanoparticles work as a gatekeeper to control release guest molecules from silica under different pH's.
Partially reduced TiO2 with highly active facets has been fabricated: Ti3+ was successfully incorporated without any additional reducing agent and surfactant, developed preferentially. The product shows improved photocatalytic activity in H2 production over previously reported material. Photocatalytic an extended time period demonstrates the stability of made by this approach.
Despite their having much greater potential for compositional and structural diversity, heterometallic metal-organic frameworks (MOFs) reported so far have lagged behind homometallic counterparts in terms of CO2 uptake performance. Now the power MOFs is full display, as shown by a series new materials (denoted CPM-200s) with superior capacity (up to 207.6 cm(3)/g at 273 K 1 bar), close all-time record set MOF-74-Mg. The isosteric heat adsorption can also be tuned from -16.4 kJ/mol...
Metal–organic frameworks (MOFs) with the highest CO2 uptake capacity are usually those equipped open metal sites. Here we seek alternative strategies and mechanisms for developing high-performance adsorbents. We demonstrate that through a ligand insertion pore space partition strategy, can create crystalline porous materials (CPMs) superior capacity. Specifically, new material, CPM-33b-Ni without any sites, exhibits comparable to MOF-74 same (Ni) at 298 K 1 bar.
Four cubic zirconium-porphyrin frameworks, CPM-99(H2, Zn, Co, Fe), were synthesized by a molecular-configuration-guided strategy. Augmentation of meso-substituted side arms (with double-torsional biphenyl rings) tetratopic porphyrin linkers leads to successful implementation zirconium-carboxylate frameworks with 2.5 nm cage. The hard-templating effect Zr6-polyoxo-cluster and uniformly embedded (metallo)porphyrin centers endow CPM-99 highly desirable properties as precursors for oxygen...
Abstract Metal-organic frameworks are a class of crystalline porous materials with potential applications in catalysis, gas separation and storage, so on. Of great importance is the development innovative synthetic strategies to optimize porosity, composition functionality target specific applications. Here we show platform for metal-organic control their sorption properties. This can accommodate large variety organic ligands homo- or hetero-metallic clusters, which allows extraordinary...
Layered double hydroxides (LDHs) have attracted broad attention as cathode materials for hybrid supercapacitors (HSCs) because of their ultrahigh theoretical specific capacitance, high compositional flexibility, and adjustable interlayer spacing. However, reported, capacitance LDHs is still far below the value, inspiring countless efforts to these ongoing challenges. Herein, a hierarchical nanocage structure assembled by NiCo-LDH nanosheet arrays was rationally designed fabricated via facile...

At first, parameter introduced into admittance disconnected line, nonlinear disconnection function constructed about parameter. After matrix are functions relevant parameters, then, used expand. The before considered as initial series, second, third...
Reported here are the new concept of utilizing open metal sites (OMSs) for architectural pore design and its practical implementation. Specifically, it is shown that OMSs can be used to run extended hooks (isonicotinates in this work) from framework walls channel centers effect capture single ions or clusters, with concurrent partitioning large spaces into multiple domains, alteration host–guest charge relationship associated guest-exchange properties, transfer centers. The hook,...
Pore space partition, especially the one using C3-symmetric 2,4,6-tri(4-pyridyl)-1,3,5-triazine as pore-partition agent in MIL-88 type (the acs net), has been shown to dramatically enhance CO2 uptake near-record values. The continued advance property engineering via pore partition would depend on intelligent design of both framework components and agent. Here, we report a new by demonstrating symmetry-guided pathway develop large variety di- trinuclear 1,2,4-triazolate-based clusters for use...
Lanthanides (Ln) are a group of important elements usually found in nature as mixtures. Their separation is essential for technological applications but made challenging by their subtly different properties. Here we report that crystallization homochiral camphorate metal-organic frameworks (MOFs) highly sensitive to ionic radii lanthanides and can be used selectively crystallize lanthanide element into predesigned MOFs. Two series MOFs were synthesized with acetate (Type 1 early La-Dy) or...
Metal-organic polyhedra (MOPs) or frameworks (MOFs) based on Cr(3+) are notoriously difficult to synthesize, especially as crystals large enough be suitable for characterization of the structure properties. It is now shown that co-existence In(3+) and induces a rapid crystal growth single heterometallic In-Cr-MOPs with [M8L12] (M=In/Cr, L=dinegative 4,5-imidazole-dicarboxylate) cubane-like structure. With high concentration protons from 12 carboxyl groups decorating every edge cube an...
Magnetic refrigeration based on the magnetocaloric effect (MCE) may provide an energy-efficient and environment-friendly alternative to conventional gas compression/expansion cooling technology. For potential applications, low-cost high-performance magnetic refrigerants are in great need. Here, we demonstrate that giant MCE can be achieved annealed Ni52Mn26Ga22 ribbons with magneto-multistructural transformation. It yields a maximum entropy change of −30.0 J kg−1 K−1 at field 5 T, being...

Abstract Cationic frameworks can selectively trap anions through ion exchange, and have applications in chromatography drug delivery. However, cationic are much rarer than anionic or neutral ones. Herein, we propose a concept, preemptive coordination (PC), for targeting positively charged metal–organic (P‐MOFs). PC refers to proactive blocking of metal sites preclude their occupation by neutralizing ligands such as OH − . We use 20 MOFs show that this concept is an effective approach...
High-silica zeolites, as exemplified by ZSM-5, with excellent chemical and thermal stability, have generated a revolution in industrial catalysis. In contrast, prior to this work, high-silica-zeolite-like chalcogenides based on germanium/tin remained unknown, even after decades of research. Here six crystalline high-germanium or high-tin zeolite-type sulfides selenides four different topologies are reported. Their unprecedented framework compositions give these materials much improved...
