Katritzky salts are used as the alkyl radical precursors with the insertion of sulfur dioxide under photoredox catalysis. This transformation first enables direct generation of various alkylsulfonyl radicals by photoinduced single electron reduction, leading to diverse dialkyl sulfones in good to excellent yields. A radical pathway is proposed under visible-light induced conditions with the insertion of sulfur dioxide.

Metal-organic frameworks (MOFs) are hybrid inorganic-organic 3D coordination polymers with metal sites and organic linkers, which are a "hot" topic in the research of sorption, separations, catalysis, sensing, and environmental remediation. In this study, we explore the molecular mechanism and kinetics of interaction of the new copper porphyrin aluminum metal-organic framework (actAl-MOF-TCPPCu) compound with a vapor of the volatile organic sulfur compound (VOSC) diethyl sulfide (DES). First, compound was synthesized by post-synthetic modification (PSM) of Al-MOF-TCPPH compound by inserting Cu ions into the porphyrin ring and characterized by complementary qualitative and quantitative chemical, structural, and spectroscopic analysis.

Electrochromic (EC) materials based on ion insertion/desertion mechanisms provide a possibility for energy storage. Solution-processable energy storage EC polyamides have great potential for use in smart displays and EC supercapacitors. A suitable monomer structure design is particularly important for enhancing the electrochemical properties of polyamides.

Lithium-sulfur batteries (LSBs) offer high energy density and environmental benefits hampered by the shuttle effect related to sluggish redox reactions of long-chain lithium polysulfides (LiPSs). However, the fashion modification of the d-band center in separators is still ineffective, wherein the mechanism understanding always relies on theoretical calculations. This study visibly probed the evolution of the Co 3d-band center during charge and discharge using advanced inverse photoemission spectroscopy/ultraviolet photoemission spectroscopy (IPES/UPS), which offers reliable evidence and are consistent well with theoretical calculations.

Sulfurized polyacrylonitrile (SPAN) has emerged as a highly promising cathode material for next-generation lithium-sulfur (Li-S) batteries primarily due to its non-polysulfide dissolution and excellent cycle stability. Nevertheless, the specific roles and impacts of the pyrolyzed polyacrylonitrile, which constitutes the polymer backbone of SPAN, remain inadequately understood. In this study, comprehensive investigations from multiple aspects, including electrochemistry, spectroscopy, electron microscopy, and theoretical calculations, were conducted on a series of SPAN materials with various sulfur contents.
