Sulfurized polyacrylonitrile (SPAN) as a cathode material has received wide interest due to the solid-solid conversion mechanism, while the Li-SPAN cell performance has been limited by the notorious issue of lithium metal anode. Developing solid-state electrolytes for lithium-sulfur batteries with favorable electrode-electrolyte compatibility is urgently desired. Herein, we demonstrate a dual-interface optimization strategy through in-situ polymerization interface construction, which synergistically enhances interfacial compatibility between the solid polymer electrolyte (SPE) and both the lithium metal anode and SPAN cathode. The initiator pre-buried in the SPE triggers the in-situ polymerization of 1,3-dioxolane (DOL) at the interface, thereby greatly reducing the electrode/electrolyte interfacial impedance. Additionally, the released fluoroethylene carbonate (FEC) into the poly-DOL interface could further reduce the impedance and enhance the interface stability during cycling, simultaneously preventing the dissolution of polysulfides, owing to the inorganic-rich and dense cathode electrolyte interphase formed on SPAN. As a result, the Li-SPAN cell could operate more than 200 cycles at 0.5C with a capacity retention of 90%.

To address this gap in our understanding, we present here the synthesis, comprehensive characterization, and reactivity of a novel thioether-ligated iron(III)-alkylperoxo complex supported by the ligand 2-((2-(pyridin-2-yl)ethyl)thio)-N,N-bis(pyridin-2-ylmethyl)ethan-1-amine.

Notably, the latter substrate reacts via the unusual aldehyde C─H bond abstraction leading to cyclohexanecarboxylic acid, which is explained by favorable aldehyde C─H abstraction transition states due to stabilizing interactions between the ligand framework and the substrate. Moreover, the reaction is initiated with a homolytic O─O bond cleavage in the iron(III)-alkylperoxo group that yields a reactive iron(IV)-oxo species that mediates substrate oxidation.

In ambipolar semiconductors, where both holes and electrons participate in conduction, distinct molecular orbitals prompt a critical inquiry: can orbital variations result in coexisting yet distinct anisotropic transport properties within a single component? We confirm this possibility by demonstrating that the air-stable nickel dithiolene, Ni(4OPr), exhibits such behavior. Despite its herringbone stacking implying a two-dimensional electronic structure, Ni(4OPr) uniquely exhibits distinct intermolecular interactions for hole (HOMO-to-HOMO; HOMO = highest occupied molecular orbital) and electron (LUMO-to-LUMO; LUMO = lowest unoccupied molecular orbital) transport. Crucially, this leads to highly anisotropic hole transport pathways, while electron pathways are remarkably isotropic, demonstrating a stark contrast in their transport anisotropies. Leveraging the high crystallinity, grazing-incidence wide-angle X-ray scattering (GIWAXS) determined in-plane molecular orientation. This enabled experimental verification of distinct anisotropic hole and electron transport, directly governed by orbital-specific intermolecular interactions, in an ambipolar molecular semiconductor.
