Four highly porous covalent organic frameworks (COFs) containing pyrene units were prepared and explored for photocatalytic H2 O2 production. The experimental studies are complemented by density functional theory calculations, proving that the unit is more active production than bipyridine (diarylamino)benzene reported previously. decomposition experiments verified distribution of over a large surface area COFs plays an important role in catalytic performance. Py-Py-COF though contains other...
One of vital issues that inhibit photoactivity metal-organic frameworks is the poor electrical conductivity. In this work, one-dimensional mixed-valence iron chains are used to improve situation in MIL-53(Fe). A series MIL-53(Fe) photocatalysts were obtained through heating at different temperatures vacuum. The effect FeII coordinatively unsaturated metal sites (CUS) and on their photocatalytic property was discussed. experimental results indicated with a reference FeII/FeIII ratio 0.2725...
Abstract Covalent Organic Frameworks (COFs) have recently emerged as light‐harvesting devices, well elegant heterogeneous catalysts. The combination of these two properties into a dual catalyst has not yet been explored. We report new photosensitive triazine‐based COF, decorated with single Ni sites to form catalyst. This crystalline and highly porous shows excellent catalytic performance in the visible‐light‐driven sulfur–carbon cross‐coupling reaction. Incorporation transition metal COF...
Three highly crystalline and porous COFs with promising photoredox properties have been prepared. Via a post-sulfurization process, the imine-linked were converted into thiazole-linked COFs, generating conjugated ultrastable photocatalyst for H 2 O production.
Abstract To develop proton‐conducting materials under low‐humidity conditions and at moderate working temperature still remains challenging for fuel‐cell technology. Here, a new type of material, EIMS‐HTFSA@MIL, which was prepared by impregnating the binary ionic liquid, EIMS‐HTFSA (EIMS=1‐(1‐ethyl‐3‐imidazolium)propane‐3‐sulfonate; HTFSA= N , ‐bis(trifluoromethanesulfonyl)amide), into mesoporous metal–organic framework, MIL‐101 ([Cr 3 F(H 2 O) O(BDC) ⋅ n H O] ( ≈0.25,...
Adsorption separation technology using adsorbents is promising as an alternative to the energy-demanding cryogenic distillation of natural gas (CH4/N2) separation. Although a few adsorbents, such metal-organic frameworks (MOFs), with high performance for CH4/N2 separation, have been reported, it still challenging target desired actual under humid conditions because adsorption capacity and selectivity might be mainly dampened by water vapor. Except CH4 uptake selectivity, material should...
Polycrystalline metal-organic framework (MOF) layers hold great promise as molecular sieve membranes for efficient gas separation. Nevertheless, the high crystallinity tends to cause inter-crystalline defects/cracks in nearby crystals, which makes crystalline porous materials face a challenge fabrication of defect-free membranes. Herein, first time, we demonstrate balance between and film formation MOF membrane through facile situ modulation strategy. Monocarboxylic acid was introduced...
Abstract Metal-organic framework (MOF) glasses are an emerging class of which complement traditional inorganic, organic and metallic counterparts due to their hybrid nature. Although a few zeolitic imidazolate frameworks have been made into glasses, how melt quench the largest subclass MOFs, metal carboxylate frameworks, remains challenging. Here, we develop strategy by grafting zwitterions on ligands incorporating acids in channels enable glass formation. The charge delocalization...
It is important to find an effective way enhance the photocatalytic efficiency of metal–organic frameworks. In this work, organic supermolecule perylene diimide (PDI) semiconductor with a carboxyl terminal was added into synthesis process MIL-53(Fe) crystals. The PDI/MIL-53(Fe) (PM) composite photocatalyst first obtained. TC-H photodegradation rate most efficient 5PM nearly 94.08% within 30 min, whose apparent reaction constant (k) 4 times that PDI and 33 MIL-53(Fe), respectively. By...

Chiral stationary phases made of readily available proline peptides were prepared and evaluated for general chiral separation. With the proper structural elements, these columns demonstrated broad selectivity. Among 53 analytes tested, a tetraproline column resolved 31. The separations achieved are comparable to those on Whelk O2 column, while still inferior Daicel AD-H OD-H columns. Number units proves important recognition, because control with single unit is largely ineffective.
Carbon dioxide capture and separation are of great importance for cutting greenhouse gas emissions. A series Zr(IV)-based MOF UiO-67-MIMS(x) (0 ≤ x ≤1) derived from mixed linkers 4,4′-biphenyl-dicarboxylate linker (BPDC) its derivative bearing imidazolium sulfonate (BPDC-MIMS) at the 2-position were designed synthesized. Their pore sizes structures well tuned by varying ratio two linkers. Binary ionic liquid moieties (MIMS/salt) furnished subsequently incorporating sodium salts within...
Abstract Purifying ultra‐high purity propylene (>99.995%) with an energy‐efficient adsorptive separation method is a promising yet challenging technology that remains unfulfilled. Instead of solely considering the effect adsorbents on guest molecules, we propose synergistic adsorption mechanism for deep removal propane and propyne, utilizing supramolecular interactions in both “host‐guest” “guest‐guest” systems. Through modulation pore environment, Ni‐DMOF‐DM exhibits exceptionally high...
A new isophthalate manganese(II) coordination polymer, [Mn3(ip)3(bipy)2]n·2nH2O (1) (H2ip = isophthalic acid and bipy 2,2′-bipyridine), with a 2D layer structure built up from isophthalato-linking trimanganese clusters, is obtained by refluxing weakly basic solution containing bipy, Mn(OAc)2·4H2O, H2ip, triethylamine.
