Invitation of organic cosolvents into aqueous electrolytes has been widely proven effective in stabilizing zinc (Zn) anodes but easily brings about sluggish desolvation kinetics concurrently. In this issue of Chem, Geng and coworkers report an organic/aqueous hybrid electrolyte with an organic-solvent-free primary solvation sheath, achieving facile desolvation and durable Zn batteries under subzero conditions.

Chemical upcycling of polyethylene (PE) waste presents a viable and promising approach to address the issues of plastic waste accumulation. However, developing cost-effective and efficient routes for converting PE waste into value-added products remains a challenging task. Here, we report a one-pot, dual-catalyst system for efficient conversion of PE into gasoline without the need for noble-metal catalysts, external hydrogen, or solvents. A gasoline yield of up to 87% is achieved over a dual-catalyst system comprising WZr-KIT-6 and HZSM-5 at 240°C. The WZr-KIT-6 catalyst facilitated the activation and pre-cracking of PE chains into unsaturated oligomers over Si-O-Zr and W-O(H)-Zr sites. These unsaturated oligomers, characterized by increased mobility and reactivity, were subsequently converted into C4–C12 gasoline-range compounds through β-scission, isomerization, and hydride transfer over HZSM-5. The synergistic reaction mechanism over mesoporous and microporous materials was crucial for enhancing the efficiency and selectivity of PE conversion.

Molecular π-magnets based on single organic molecules have attracted increasing attention for their potential applications in optoelectronics and spintronics. Global aromaticity in conjugated macrocyclic polyradicaloids is still an open question that has only been tackled in molecules with an even number of electrons. Here, we report the on-surface synthesis of a cyclopenta-ring-fused oligo(m-phenylene) macrocycle, 9MC, with an odd number of electrons. The generated polyradicaloid undergoes a surface-induced distortion to a D3h symmetry with a fully delocalized doublet ground state. Interestingly, 9MC exhibits two aromatic annulene-within-an-annulene (AWA) ring currents in the inner and outer rings.

The installation of stimuli-responsive moieties into their main chain maximizes the stimuli response of polymers. Yet, facile and orthogonal synthesis of such complex macromolecules is a daunting challenge, especially for achieving absolute chain-end-group fidelity, monodispersity, and the formation of block copolymers (BCPs). We harness metal-free hydroxyl-yne click and deprotection chemistry to realize monodisperse, sequence-defined oligomers and BCPs featuring α-bisimines as main-chain photoswitches and orthogonally incorporate functional terminal groups (olefins, acrylates, and non-activated alkynes). We reveal the significant influence of the sequence on solution and solid-state material properties, which manifests as a strong odd-even effect on the hydrodynamic volume, glass transition temperature, and BCP domain spacing. The odd-even effect originates from the distinct symmetries of the sequences resulting from our precise synthetic strategy. Thus, our sequence-defined, orthogonal synthesis strategy with near absolute chain-end-group fidelity and wide functional group compatibility paves the way toward complex polymeric materials with precise properties, topology, composition, and main-chain functionalities.

The practical application of Zn-based batteries is compromised by rampant dendrite growth, unfavorable side reactions, and serious capacity decay. We report a trifunctional glutarimide (Glu) electrolyte additive to stabilize the electrochemical reaction of the Zn anode and facilitate redox activity of the cathode. Theoretical calculations and spectroscopic characterizations reveal that Glu with the electron-withdrawing/donating capability can substitute partially coordinated water and manipulate the solvation structure by reinforced ion-dipole interactions. Meanwhile, Glu can form a solid electrolyte interphase layer and alleviate parasitic reactions. Consequently, Glu renders excellent Zn plating/stripping cycling of 2,000 h at 1 mA cm−2/1 mAh cm−2. Even at an ultra-high depth of discharge of 85.2%, a stable cycling of 138 h is obtained. The formulated additive serves as the charge redistributor and decouples the cation-anion interaction to stabilize the interaction of ClO4− with the half-oxidized protonated polyaniline, enabling the Zn-organic battery with enhanced energy storage performance.

Molecular-level structural modification is a well-established approach to impart advanced functionality to materials that continues to be the focus of research and development in both academic and industrial laboratories. Here, we report the synthesis of an ordered two-dimensional (2D) poly[2]catenate from the simultaneous self-assembly of two organic ligands and a metal salt by the formation of catenate links using metal coordination and imine condensation reactions. Subsequent chemical reduction of the imine bonds generated the corresponding demetallized poly[2]catenane, which was found to have greater non-rigid-body-like character than the poly[2]catenate as a result of the increased internal dynamics of the mechanical bonds and resulted in an 8-fold increase in elasticity. This synthetic approach allowed for the efficient incorporation of mechanically interlocked molecules (MIMs) within a 2D ordered structure and demonstrated their importance in improving the physical properties of materials by accessing molecular degrees of freedom that cannot be achieved by other means.

Constructing artificial sophisticated architectures from simple small-molecular subunits by cooperative interactions remains one of the most formidable challenges. Herein, we report a complex supramolecular structure, {{[CoL(SCN)]20}{[CoL(SCN)]24}3(SO4)23(HSO4)46}·246(CH3CN) (1), that arises from the assembly of [CoL(SCN)]+ with SO42− and HSO4− (L = tris(2-benzimidazolylmethyl)amine) under solvothermal condition. The crystallization of compound 1 is driven by the cooperation of the π-π stacking interactions between [CoL(SCN)]+ cations and the hydrogen bonds between [CoL(SCN)]+ and SO42− and HSO4−. [CoL(SCN)]+ cations self-associate through intermolecular π-π stacking interactions to create two π-stacked polyhedral 512-{[CoL(SCN)]20} dodecahedra and 51262-{[CoL(SCN)]24} tetrakaidekahedra. These two π-stacked polyhedral subunits coexist in the same lattice in a 1:3 ratio and coordinate with SO42− and HSO4−, resulting in a complex Frank-Kasper (FK) A15 structure. This research demonstrates that small-molecular scaffolds can assemble into sophisticated architectures and creates exciting perspectives for constructing sophisticated clathrate structures from simple small molecules.
