Summary: Polyanhydrides based on betulin are promising materials for controlled drug delivery systems due to their broad biological activity and non-toxicity in vitro and in vivo. This study focused on the development of novel amphiphilic branched polyanhydrides, which showed higher anticancer activity compared to linear polyanhydrides. The branched polyanhydrides were able to self-assemble into stable micelles, making them potential candidates for biodegradable polymer prodrugs or carriers for other bioactive compounds.

Summary: A highly stable Zn metal anode is designed by reconstructing its surface with a self-assembled nanoporous polyelectrolytic interlayer. This layer acts as a physical barrier reducing the contact between Zn metal and water molecules, suppressing hydrogen evolution and Zn corrosion. The unique nanostructures and chemical compositions of the interlayer ensure fast Zn plating/stripping kinetics and homogeneous growth of Zn deposits, resulting in significantly prolonged cycle life and low voltage hysteresis.

Summary: This work successfully prepared CsPbBr3/Cs4PbBr6 core/shell nanocrystals with high photoluminescence quantum yields (87.23%) and long-term stability in ambient environments using a room temperature inverse microemulsion method. The stability was attributed to the protection of Cs4PbBr6, while the high photoluminescence quantum yields were due to the passivation effect of the core/shell structure.

Summary: Amorphous chromium oxide confined Ni/NiO nanoparticles-assembled nanosheets were synthesized through an in-situ confined synthesis method, which showed fast reaction kinetics for urea oxidation reaction (UOR). The confinement effect of the in-situ generated CrOx overlay resulted in ultrafine Ni/NiO nanoparticles and rich interfaces. Both CrOx and metallic Ni promoted the formation of NiOOH species and electron transfer, leading to high intrinsic activity and fast reaction kinetics. The protective effect of the CrOx overlay also ensured robust working stability for UOR. Moreover, the Ni/NiO@CrOx nanosheets served as bifunctional catalysts for overall urea splitting with a low electrolysis cell voltage.

Summary: A new type of coordination-driven cuboctahedron cage was presented to study the fluorescent behavior of quantitatively confined aggregation-induced emission (AIE) molecules in a giant cavity. The cage, with 12 AIE molecules anchored endohedrally linked with different-length alkyl chains, exhibited strong fluorescence in highly diluted conditions. The fluorescence quantum yield could be altered by prolonging the length of alkyl chains. This study has great potential applications in biology mimic and fluorescent microscopes utilizing confined or isolated fluorescent methods.

Summary: In this study, a decametric metal-organic cage, pentagonal prism Mn20LC10, was developed based on Tpy-Mn(II)-Tpy connectivity, with Mn(II) serving as a linker to provide good photosensitivity. This metal-organic cage exhibited enhanced 1O2 production, fast conversion time, recyclability, and substrate versatility in the photooxidation of benzaldehyde due to improved intersystem crossing ability. Remarkably, the abundant active sites of Mn20LC10 enabled its photooxidation under solvent-free and daylight conditions. This work offers potential approaches for the development of inexpensive, green, and low-cost photosensitizer systems.

Summary: We report a terpyridine-based metallo-cage that can undergo controlled hierarchical self-assembly of superstructures in response to different halide ions. By adding Cl-/Br- or I-, drastically different hierarchical superstructures with highly-tight hexagonal packing or graphite-like packing arrangements, respectively, have been achieved. These unusual halide-ion-triggered hierarchical structural changes provide new insights into the mechanism of supramolecular aggregation and crystal growth.

Summary: In the field of metallo-supramolecular assemblies, supramolecular macrocycles with guest recognition and catalytic properties have attracted attention. This study presents a novel strategy for constructing giant hollow macrocyclic structures using a bi-directional geometric constraint strategy. By designing two terpyridine-based tetratopic organic ligands with different angles, the mutual interaction between the ligands promotes the formation of giant hollow macrocyclic supramolecular architectures. The self-assembly mechanism and hierarchical self-assembly of the giant supramolecular macrocycles are characterized by NMR, ESI-MS, and TEM experiments.
