Summary: An unreported spike with a line-width similar to mu s was discovered at the rising edge of transient electroluminescence from guest-doped organic light-emitting diodes, which is not related to exciton interactions but originates from the radiative recombination of pre-stored electrons with injected holes due to the strong electron-donating abilities of the host carbazole groups. The spikes show rich and extraordinary temperature dependences, and artificial adjustments of the spike intensity have been proposed based on the understanding of the spike formation mechanism.

Summary: Developing materials that can differentiate between chemically similar substances is challenging, especially for aliphatic and aromatic amines. Metal-organic frameworks (MOFs) with permanent porosity have been designed for discriminative sensing of amines and on-site detection of ammonia. Two Co-based multifunctional MOFs were utilized, where aliphatic amines led to turn-off fluorescence and aromatic amines showed turn-on fluorescence intensities. Real-time sensing experiments with MOF-based mixed matrix membranes demonstrated an instant color change when ammonia was released.

Summary: Covalent organic frameworks (COFs) have received much attention recently due to their excellent molecule recognition and chemical sensing capabilities. However, the utilization of COFs-based sensors is hindered by processing and forming difficulties. In this study, a composite material is designed by combining polyacrylamide (PAM) as a matrix and TFP-PPDA COF as reinforcement, resulting in a PAM/TFP-PPDA composite nanofibrous membrane (NFM) prepared using electrospinning technology. The PAM/TFP-PPDA composite demonstrates effective fluorescence sensing of volatile organic compounds (VOCs) and specifically detects primary aliphatic amine through a fluorescence enhances (turn-on) effect.

Summary: This study introduces a novel emission strategy from a 2D ionic hydrogen bond supramolecular network, with high-quality crystals obtained from rapid self-assembly of liquid amine and ketone. The charge-separated transition process and high spin-orbital coupling constants in the rigid supramolecular structure contribute to enhanced singlet-triplet intersystem crossing, leading to stable room-temperature phosphorescence with a maximum quantum efficiency of 26% and a lifetime of 0.45 s. These findings will bring fresh thinking to photoluminescence and other functions purely originated by the supramolecular structure.

Summary: The electrical vapor sensor based on carbon nanotubes (CNTs) has gained wide attention due to its excellent conductivity and stable interfacial structure. However, limited performance was observed due to the random distribution of coated CNTs. A new strategy was developed to align the CNTs using fractal designing of the electrode system. This led to higher carrier mobility and an ultrasensitive vapor sensor with a detection limit of 0.998 ppq.

Summary: Fluorescent film sensors are widely used for detecting toxic gases, but the design and synthesis of high-performance sensitive materials are complex. This study demonstrates that the sensing performance of fluorescent sensors can be enhanced by simply growing or depositing zinc oxide film on a quartz substrate. The catalytic properties of the zinc oxide buffer effectively accelerate the sensing process between the probe molecules and H2O2 gas.

Summary: Most current studies on diagnosing diseases through exhaled gas only focus on single markers, but there are actually biomarkers with similar properties corresponding to different diseases. Existing sensing techniques cannot achieve simultaneous multi-label classification of the targets. By introducing multiple hydrogen bond receptors and adjusting the aromatic ring end group, the strength of the interaction between target molecules and the sensor array can be modulated. Sensor responses related to molecular structure can be used as detection characteristics. Through machine learning, different types of amines can be successfully identified, and this method can also distinguish mixed amines at different concentrations in the range of ppm-ppb.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
