A design concept involving introduction of sp³-hybridized nitrogen atom to conjugated organic linkers leads to intrinsic hole mobility in a luminescent metal–organic framework (MOF). The triarylamine-based MOF (Zr-NBP) has strong fluorescence and high hole mobility of 1.05×10⁻⁶ cm² V⁻¹ s⁻¹. A thin film of Zr-NBP in pure phase was used directly as an emissive layer (EML) and a hole-transporting layer (HTL) in OLED devices.

Ostwald ripening is used for reducing particle size in miniemulsions, providing a rapid and versatile method to synthesize silica nanocapsules with an ultrasmall size (ca. 6 nm) and a well-defined core–shell morphology, even at low surfactant concentration. Aqueous solubility of solvents and reactivity of alkoxysilanes used in the synthesis are the key factors in controlling the formation of ultrasmall nanocapsules.

We propose an environmentally-friendly route for the synthesis of crystalline covalent organic frameworks (COFs) from CO₂ molecules as a precursor. Two-step reactions using NaBH₄, piperazine and melamine with CO₂ provided high crystalline structure. The CO₂-derived COF has a 3-fold interpenetrated structure showing a BET surface area of 945 m² g⁻¹ and structural integrity. This structure transforms to high proton conductor upon post-modification reaction with Oxone.

Heart of glass: The liquid/glass states of coordination polymers (CPs) and metal-organic frameworks (MOFs) constitute a new class of amorphous materials and are related to ionic liquids and other ionic soft materials. The unique energy landscape and dynamics of liquid/glass CPs/MOFs with coordination networks offer additional opportunities for properties and functions that are complementary to those of the crystalline state.

Recently, fossil fuel consumption has led to petroleum shortages and high carbon emissions. Thus, this study explores renewable resources for the electrochemical synthesis of 2,5-furandicarboxylic acid (FDCA) and carbon monoxide (CO), from hydroxymethylfurfural (HMF) and carbon dioxide (CO₂), respectively, using Fe/Ni-supported carbon nanotubes (CNTs) catalysts derived from CO₂, achieving a faradaic efficiency of FDCA as 99.60% and 96.25% for CO.

In for a shock: The electric potential of a mesoporous chiral platinum phase can be tuned to allow quantitative separation of the enantiomers in a tryptophan racemate. An applied potential influences the electrostatic interactions, and thereby the enantioaffinity, between the chiral metal and the target enantiomer.

MG8, a novel polyethylene-terephthalate (PET) hydrolase from the human saliva metagenome, with robust PET degradation activity, was discovered and characterized. It was further repurposed into a covalent binder of PET through genetic code expansion, enabling its use to attach protein payloads to PET and other polyesters under mild conditions.

Biogenesis of amyloid-β peptides from their precursor protein can be tracked in endocytic compartments of living cells by a molecular beacon labeling strategy based on genetic code expansion.

Electrophilic halogenases in nature are typically not efficient. Guided by flavin-dependent halogenase mechanisms and taking advantage of the versatile reactivity of a flavin hydroperoxide adduct and in situ generation of H₂O₂ by flavin-dependent enzymes, it was possible to promote the formation of a hypohalous acid—which is key for electrophilic halogenation—in various non-native halogenases by rerouting the flavin-generated peroxide.

Enzymatic reactions were developed to convert 19 phenolic derivatives containing halogen, nitro, and methyl substituents into eight D-luciferin analogues, including the novel compounds 4′,5′-dimethyl-D-luciferin and 5′-methyl-D-luciferin, which emit brighter and longer-wavelength light than the native D-luciferin. These reactions enabled the further development of luminescence technology for the sensitive detection of organophosphate pesticides.

An efficient and green method is presented for the synthesis of esters using carboxylic acid reductase as a biocatalyst under mild aqueous conditions.

A chemo-enzymatic cascade was developed to convert nitro- and halogenated phenols into d-luciferin, a valuable chemical widely used in biomedical applications. The reaction can be further coupled with firefly luciferase to generate bioluminescence. This integrative biodetoxification–biosynthesis platform can be used to detect these toxicants without the requirement for pre-treatment.

A spoonful of sugar: A new concept for the synthesis of l-ribulose from l-arabinose was successfully established using a one-pot bioconversion consisting of engineered pyranose 2-oxidase, xylose reductase, formate dehydrogenase, and catalase. Transient kinetics in combination with molecular dynamics simulations indicate that the sugar substrate is positioned closer to the FAD N5-position in the engineered pyranose 2-oxidase than in the wild-type.
