Summary: This study reports an unprecedented, single isomer styryl-functionalized T-18 POSS, which has been unambiguously identified among nine possible isomers using multinuclear solution NMR, MALDI-MS, FTIR, and computational studies. A ring-strain model was developed to predict the speciation of non-equivalent Si atoms in other T-n compounds, demonstrating its general applicability and usefulness for predicting Si-atom environments.

Summary: The remineralizing potential of hydroxyapatite has led to its use in dental composites. However, the compatibility between hydroxyapatite and organic compounds is insufficient, resulting in low mechanical properties. Polyhedral oligomeric silsesquioxanes show promise as additives to dental composites, and their modification of hydroxyapatite surfaces improves mechanical properties and reduces water sensitivity.

Summary: There is a growing demand for functional silica-based porous materials in the market. In this study, a PEG-linked bis-imidazolium chloride silsesquioxane (PIMAILS) was functionalized on polyhedral oligomeric silsesquioxanes (POSS) to create a highly porous ionic liquid adsorbent. The adsorbent exhibited a high surface area and continuous porous structures, making it effective in removing Cr(VI) ions from wastewater.

Summary: The functionality of traditional materials can be modified by using polyhedral oligomeric silsesquioxanes (POSSs) due to their unique cage-like structures. In this study, fluorinated POSSs were introduced into hyperbranched white-emitting polymers based on polyfluorene (PF) with spiro[3.3]heptane-2,6-dispirofluorene (SDF) as the branching center. The results showed that the fluorinated POSSs maintained the amorphous morphology of the polymer film, improved its thermal stabilities and hydrophobicity, and enabled the realization of white light-emitting polymer devices with good electroluminescent (EL) performance and high color saturation.

Summary: ε-Thionocaprolactone (TCL) can be easily copolymerized with vinyl esters to form degradable copolymers, with the molecular weight and dispersity controlled through xanthate-mediated RAFT polymerization. Analysis of the copolymer structure reveals a high level of TCL-TCL dyads, suggesting that the terminal copolymerization model is not accurate for describing TCL copolymerization.

Summary: A unique 3D interconnected Si/SiOx/C nanorings were successfully fabricated via AlCl3-assisted aluminothermic reduction, showing great potential in the field of lithium ion batteries. The obtained nanorings exhibited uniform diameter and well distribution of C and Si elements, along with superior high-rate capacity and good cycle stability as an anode for LIBs. Furthermore, they delivered high reversible capacity at ultra-low temperature, broadening the application possibilities of POSS.

Summary: This study presents an integrated platform that combines a miniaturized filter-aided sample preparation method with high-pH reversed phase or strong cation exchange microreactors for efficient sample preparation and fractionation prior to LC-ESI-MS/MS analysis. The platform generated a large number of unique peptides and protein groups, comparable to state-of-the-art methods, but with reduced cost and time. This integrated platform has significant potential in deep proteomics analysis of mass-limited samples.

Summary: We have developed a new protocol for determining D/L amino acids using a chiral phosphinate derivatization. (RP)-L-Menthyl phenylphosphinate successfully labeled eighteen pairs of amino acids except for Cys, and the chirality of amino acids was discriminated by 31P NMR. Seventeen pairs of amino acids were separated in 45 minutes using a C18 column, with resolution values ranging from 2.01 to 10.76. The lowest limit of detection was 10 pM in parallel reaction monitoring, highlighting the potential of chiral phosphine oxides in future chiral metabolomics.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
