Summary: Discrete polymers are a valuable tool for studying chain structure, self-assembly behavior, and functional applications. However, the development of discrete polymers with self-immolative properties is limited. In this study, we synthesized a library of self-immolative oligourethanes through stepwise growth, which exhibited cascade depolymerization and selective cleavage properties. These oligourethanes also displayed different morphologies and morphological transitions in aqueous media and upon thermal annealing.

Summary: Featuring molecule-level data encryption, molecular keypad locks offer attractive advantages in information security. Previous multiple-input locks using fluorescence as the output have encountered challenges due to inefficient prequenching or the synthetic complexity of fluorophore-containing processor molecules. In this study, we propose a simple and label-free three-input molecular keypad lock, capable of generating fluorescent readout without background interference. The correct password leads to the generation of a fluorescent product, while incorrect inputs fail to open the lock. This device shows potential for further development into an advanced and secure keypad lock.

Summary: Peroxynitrite (ONOO-) is an important reactive oxygen/nitrogen species (ROS/RNS) that plays a vital role in physiological activities. Excessive ONOO- is associated with various diseases, including inflammation, arthritis, inflammatory bowel disease, cancer, and neurodegenerative diseases. In this study, a chemiluminescent probe, B-PD, was designed and synthesized to detect endogenous ONOO-. The probe showed a quick response and a detection limit of 201 nM. In vivo imaging results demonstrated that B-PD could effectively locate early stage inflammation tissue with a high imaging contrast of up to 6.2. These findings suggest that B-PD holds great promise for highly sensitive diagnosis of inflammation-related diseases in the future.

Summary: By using density functional theory calculations, the potential catalytic performance of single transition-metal (TM) atoms supported on nitrogenated holey doped graphene (g-C2N) for electrocatalytic reduction of nitrate (NO3RR) to synthesize ammonia (NH3) was investigated. Zr/g-C2N and Hf/g-C2N were predicted as potential electrocatalysts for NO3RR with limiting potential (UL) values of -0.28 and -0.27 V, respectively. The generation of byproducts such as dioxide (NO2), nitric oxide (NO), and nitrogen (N2) was hindered on Zr/g-C2N and Hf/g-C2N due to high energy cost.

Summary: In this study, single-atom catalysis on two-dimensional graphene and electride heterostructures was investigated using first-principles calculations. The electron gas in the electride layer facilitated a significant transfer of electrons to the graphene layer, which could be controlled by the choice of electride. The charge transfer effectively modified the d-orbital electron occupancy of a single metal atom, leading to enhanced catalytic activity for hydrogen evolution and oxygen reduction reactions. The strong correlation between adsorption energy and charge transfer suggested that interfacial charge transfer is a crucial catalytic descriptor for heterostructure-based catalysts. The polynomial regression model demonstrated the importance of charge transfer and accurately predicted the adsorption energy of ions and molecules. This study offers a strategy for obtaining high-efficiency single-atom catalysts using two-dimensional heterostructures.
