Summary: This study elucidates the aggregation mechanism of AIE-active complex 1 from the perspective of supramolecular self-assembly, revealing the self-assembly process through real-time monitoring of emission and absorption fingerprints at different wavelengths. Concentration-dependent and temperature-dependent spectral studies show the transition of 1NP to 1NS, and successful living supramolecular polymerization with highly controllable sizes was achieved. Through in-depth study of intermolecular interactions, the formation of two-dimensional nanosheets was attributed to electrostatic interactions in the [010] direction and abundant non-covalent interactions in the [100] direction.

Summary: In this work, a series of butterfly-like isomers named oxacalix[2]naphthalene[2]pyrazine (ONP) were synthesized conveniently by a one-step catalyst-free reaction, showing typical characteristics of aggregation-induced emission (AIE). The AIE properties of ONP can be attributed to the restriction of intramolecular vibration (RIV). The coordination ability of ONP molecules with pyrazine groups makes them ideal ligands for constructing luminescent metal-organic frameworks (MOFs), and different ONP isomers have different binding capacities.

Summary: By lattice and band engineering, Zhang et al. constructed a unipolar barrier avalanche photodiode with suppressed dark current and reinforced reverse breakdown. Ga2O3-based solar blind avalanche photodetectors exhibit low voltage operation, optical filter-free and monolithic integration of photodetector arrays, and therefore they are promising to be an alternative to the bulky and fragile photomultiplier tubes for weak signal detection in deep-ultraviolet region. These findings provide insights into precise manipulation of band alignment in avalanche photodetectors, and also offer exciting opportunities for further developing high-performance Ga2O3-based electronics and optoelectronics.

Summary: Currently, most three-terminal neuromorphic devices only have an active gate terminal, limiting the implementation of complex neural behaviors and brain-like thinking strategies. In this study, we utilize the unique co-existing in-plane and out-of-plane ferroelectricity in 2D & alpha;-In2Se3 to create a three-active-terminal neuromorphic device with each terminal capable of modulating conductance. Through the cooperative mode, we achieve control of food intake as a complex nervous system-level behavior and implement reinforcement learning using the coupling effect between polarizations in different directions. The practicality of three-active-terminal neuromorphic devices in handling complex tasks and their potential for implementing brain-like learning strategies are demonstrated.

Summary: As an emerging family of 2D nanomaterials, early transition metal carbides and carbonitrides (MXenes) have shown great potential in various applications. Research on MXene-based polymer nanocomposites has gained increasing attention due to their improved oxidation and damage tolerance. MXenes can enhance the mechanical properties and provide desired thermal/electrical properties to polymer. The assembly of MXene nanosheets into MXene macrostructures (MMs) is an effective strategy to optimize the performance of the nanocomposites. This review summarizes recent research progress on MMs/polymer nanocomposites, focusing on the relationships among structures, fabrication techniques, and performance. It also discusses the applications of these nanocomposites in heat/electrical conduction, electromagnetic shielding, and flexible devices. Challenges and future perspectives for multifunctional MMs/polymer nanocomposites are also highlighted.
