Hydrophobic membranes infused with mixed solvents including a low polar solvent and a specific solvent can efficiently separate analytes from blood upon applying a voltage. In contrast, membranes infused with a specific solvent alone show significantly reduced separation efficiencies for blood samples. Infusion of a low polar solvent is of importance for achieving antifouling ability of membranes for biological sample pretreatment. [ABSTRACT FROM AUTHOR]

Herein, we report an organometallic framework (OMF) generated from a divergent tridentate arylisocyanide ligand and PdI2 under solvothermal conditions. The obtained Pd–C bond-connected two-dimensional Pd-OMF was crystalline and porous. Moreover, it could be a highly active catalyst to promote the Suzuki–Miyaura cross-coupling reaction in a heterogeneous manner. [ABSTRACT FROM AUTHOR]

A novel Pd(ii)–Pb(ii) bimetallic metal–organic framework Pd(ii)–Pb(ii)–MOF (B) which contains an N-heterocyclic tetracarbene Pd(ii) moiety was synthesized based on a chelating N-heterocyclic dicarbene Pd(ii)–NHDC ligand (A) under solvothermal conditions. It can be a highly active heterogeneous catalyst for three-component cyclotrimerization via benzyne species. [ABSTRACT FROM AUTHOR]

Hydrophilic graphene oxide (GO) nanosheets can be easily coated onto stainless steel meshes. Compared to neat meshes, GO coated meshes become more hydrophilic in air and superoleophobic under water. Taking advantage of this completely opposite wettability, GO coated meshes were used for gravity-driven oil–water separation. [ABSTRACT FROM AUTHOR]

A new Cu-catalyzed thioorganic–boronic acid desulfitative C–C bond-forming reaction involving ketene dithioacetals/ vinylogous thioesters is reported to proceed without the assistance of ligating S-pendant. Vinylogous thiolesters and tetrasubstituted olefins were prepared by this reaction in which Cu catalyst plays a dual role under aerobic conditions. [ABSTRACT FROM AUTHOR]

The first 3D uninodal eight-connected {P4Mo6O31H6}-based pure inorganic framework linked by transition metal ions has been synthesized and its electrochemical behavior and diffuse reflectance UV-Vis spectrum were investigated. [ABSTRACT FROM AUTHOR]

A stable mesoporous blue-emitting MOF NENU-521 was successfully constructed. NENU-521 can serve as a host for encapsulating Alq3 to obtain tunable and efficient white-light emission. The Alq3@NENU-521 composite possesses excellent stability and can be used as a promising white phosphor in WLEDs. [ABSTRACT FROM AUTHOR]

A cascade recycling amplification (CRA) that implements cascade logic circuits with feedback amplification function is developed for label-free chemiluminescence detection of microRNA-122 with an ultrahigh sensitivity of 0.82 fM and excellent specificity, which is applied to construct a series of molecular-scale two-input logic gates by using microRNAs as inputs and CRA products as outputs.

Inhibition of the dioxygen sensing hypoxia-inducible factor prolyl hydroxylases has potential therapeutic benefit for treatment of diseases, including anaemia. We describe the discovery of a small-molecule probe useful for monitoring binding to human prolyl hydroxylase domain 2 (PHD2) via fluorescence polarisation. The assay is suitable for high-throughput screening of PHD inhibitors with both weak and strong affinities, as shown by work with clinically used inhibitors and naturally occurring PHD inhibitors.

A UiO-66-MOF-based membrane UiO-66-TEM (1) was prepared by the assembly of methacrylamide-decorated UiO-66-NH-Met with a thiol side chain-attached polysiloxane (PSI-SH) via a photoinduced thiol–ene click reaction. The obtained membrane 1 can be a platform to support Au nanoparticles (Au NPs) to generate an Au–MOF–polymer composite membrane Au@UiO-66-TEM (2). 1 and 2 can be used to build highly efficient continuous flow-through membrane reactors for Knoevenagel condensation of 4-nitrobenzaldehyde with malononitrile and 4-nitrophenol (4-NP) reduction at ambient temperature, respectively.

Polysubstituted phenols are efficiently assembled from one aldehyde and two different methyl ketones in a one-pot operation viaa newly base-induced regiospecific [4 + 1 + 1] annulation and sequential metal-free oxidative aromatization using molecular oxygen (from air) as the sole oxidant at room temperature.
