Cation-controlled catalysis with crown ether-containing transition metal complexes
This Feature Article reviews the structural motifs and catalytic applications of crown ether-containing catalysts and details the development of “pincer-crown ether” ligands for applications in controlled catalysis.
The application of click chemistry for targeting quadruplex nucleic acids
The Cu(I)-catalyzed azide and alkyne 1,3-dipolar cycloaddition (CuAAC), commonly known as the “click reaction”, has emerged as a versatile synthetic tool for targeting quadruplex nucleic acids.
Photoactive supramolecular cages incorporating Ru(II) and Ir(III) metal complexes
Cage compounds incorporating phosphorescent Ru(II) and Ir(III) metal complexes possess a highly desirable set of optoelectronic and physical properties. This feature article summarizes the recent work on cage assemblies containing these metal complexes as photoactive units, highlighting our contribution to this growing field.
Silicon incorporation in polymethine dyes
Incorporation of silicon into heterocycles for polymethine dyes can impart red-shifts of up to 100 nm, while also enhancing photostability up to 10-fold, resulting in photostable fluorophores with emission above 900 nm.
Selective sensing of THC and related metabolites in biofluids by host:guest arrays
A host–guest fluorescence sensor array can selectively detect THC and its metabolites in biofluids such as urine and saliva.
Template-guided selection of RNA ligands using imine-based dynamic combinatorial chemistry
This study establishes the applicability of imine-based dynamic combinatorial chemistry to discover non-covalent ligands for RNA targets.
Bioadhesive supramolecular hydrogel from unprotected, short D,L-peptides with Phe-Phe and Leu-Asp-Val motifs
Minimalistic and uncapped D,L-peptides self-assemble into bioadhesive hydrogels that successfully mimic the extracellular matrix and lead to high cell viability.
Antiaromaticity gain increases the potential for n-type charge transport in hydrogen-bonded π-conjugated cores
Hydrogen bonding increases antiaromaticity and lowers the LUMO energy levels of non-aromatic π-conjugated cores.
Extremely twisted and bent pyrene-fused N-heterocyclic germylenes
The first examples of pyrene-fused Janus-type N-heterocyclic germylenes (NHGe) are reported.
Sensing of citrulline modifications in histone peptides by deep cavitand hosts
A host–guest fluorescence sensor array can site-selectively sense histone peptide modifications that change only a single atom in the peptide backbone.
A supramolecular sensor array for selective immunoglobulin deficiency analysis
A host–guest based fluorescence sensor array can fully discriminate five structurally similar Ig protein isotypes, and recognize Ig deficiencies in serum.
Size dependent selectivity of Cu nano-octahedra catalysts for the electrochemical reduction of CO2 to CH4
Octahedral Cu nanocrystals in the size range of 75–310 nm are synthesized and investigated for electrochemical CO2 reduction.
Outstanding reversible H2S capture by an Al(III)-based MOF
MIL-53(Al)-TDC was demonstrated to be an optimal adsorbent for acidic H2S capture combining an unprecedented uptake at room temperature, excellent cyclability and low-temperature regeneration.
s-Block carbodicarbene chemistry: C(sp3)–H activation and cyclization mediated by a beryllium center
The first examples of carbodicarbene (CDC)-s-block complexes have been synthesized. Unusual C–H bond activation and cyclization discovered.
Heavy interstitial hydrogen doping into SrTiO3
We first report the heavy interstitial hydrogen doping and metallization of otherwise highly insulating SrTiO3 by hydrogen ion beam irradiation.
Self-assembly of penta-selenopeptides into amyloid fibrils
Here, we report the synthesis of a penta-selenopeptide consisting of five benzyl protected selenocysteine residues.
Asymmetrical etching of Ag nanoparticles into symmetry-reduced bi-metallic nanocups at the single-nanoparticle level
By employing the water/air interface-confinement effect, local nanomasking and thus selective etching were achieved on single interfacial nanoparticles, developing a series of symmetry-reduced cubic, spherical, trough-like nanocups.
Covalent switching, involving divinylbenzene ligands within 3D coordination polymers, indicated by changes in fluorescence
Reversible single-crystal-to-single-crystal transformations of two photo-responsive three-dimensional coordination polymers exhibit green/blue and green/blue-green fluorescence switching behaviors.
Chemoselective epoxidation of cholesterol derivatives on a surface-designed molecularly imprinted Ru–porphyrin catalyst
High chemoselectivity for the C5C6 epoxidation of cholesterol derivatives without protecting other oxidizable functional groups was achieved on a newly designed molecularly imprinted Ru–porphyrin catalyst using a SiO2-support.
Tuning the structure and catalytic activity of Ru nanoparticle catalysts by single 3d transition-metal atoms in Ru12–metalloporphyrin precursors
The single 3d metal atoms at the central position of the Ru12–metalloporphyrin complex precursors exerted a significant influence on the structure and hydrogenation performance of the Ru nanoparticles on the SiO2 surface.
Aqueous phase sensing of cyanide ions using a hydrolytically stable metal–organic framework
A fluorescent bio-compatible anionic metal–organic framework (MOF) for pure aqueous phase recognition and detoxification of cyanide ions (CN−) has been reported. The MOF acts as a molecular reaction vessel exclusively for cyanide ions, inducing a signal turn on response in aqueous media.
