Ultrastable Self‐Cross‐linkable Electro‐Optic Materials Based on a Bisanthracene Scaffold

Advanced Electronic Materials, EarlyView.
A novel bisanthracene‐based self‐cross‐linkable electro‐optic chromophore (TD2) is developed. TD2 exhibits a high r33 of 141 pm/V and a cross‐linked Tg up to 195 °C, retaining 99.75% of its initial EO response after 500 h at 85 °C, showing record‐high thermal stability for single‐molecule self‐cross‐linking EO materials.

Poly(aniline boronic acid): A New Precursor to Substituted Poly(aniline)s [PDF]

, 2001
A novel strategy for preparing a wide range of substituted poly(aniline)s from a single precursor is described. This approach relies on a boron activation/electrophilic displacement reaction resulting in ipso-substitution.

Oxidation of aniline using different reaction pathways [PDF]

, 2008
The goal of this study is to cleavage of aromatic ring of aniline to minimize its hazardous environmental effects. Therefore a method has been developed to remove aniline using potassium dichromate as an oxidizing agent.

Strain‐Release Pentafluorosulfanylation of Carbonyl‐Containing Disubstituted Bicyclobutanes: A Fortuitous Path to SF5‐Containing Oxa[2.1.1]bicyclohexanes

Angewandte Chemie, EarlyView.
A regio‐ and diastereoselective method for strain‐release pentafluorosulfanylation of carbonyl‐containing 1,3‐disubstituted [1.1.0]bicyclobutanes (BCBs) was developed that led to several fortuitous discoveries. For instance, the resultant SF5‐cyclobutanes (SF5‐CBs) exhibit close SF5⋯C═X contacts (X = C, N, O) and provide synthetic access to a new class

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Selective Degradation of Polyurethanes in Mixed Plastic Wastes via Ir‐Catalyzed Hydrogenolysis

Angewandte Chemie, EarlyView.
The selective degradation of polyurethanes in mixed plastic wastes with polyesters and polyamides was achieved using H2 as a reactant, enabling simultaneous recovery of diformamides and polyols arising from polyurethanes and separation of polyesters and polyamides without any degradation.

Chemical polymerization of aniline in phenylphosphinic acid [PDF]

Journal of the Serbian Chemical Society, 2005
The chemical polymerization of aniline was performed in phenylphosphinic acid (APP) medium using ammonium peroxidisulfate as the oxidizing agent, at 0 ºC and 25 ºC. The yield of polyaniline (PANI) was about 60–69 %. The polymerization process required an

Molecular Engineering of Polytriphenylamine: A Fluorinated Cathode for High‐Voltage, Ultrafast, and Stable Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Fluorination of polytriphenylamine lowers the HOMO energy, enabling high‐voltage operation of the PFTPA cathode. Electron‐withdrawing F substituents stabilize the nitrogen redox center and suppress polarization, leading to fast kinetics. The optimized polymer delivers ∼3.75 V vs.

Positive Electrochemical Potentials Induce Enhanced Chemoselectivity and Activity in the Thermocatalytic Hydrogenation of 3‐Nitrostyrene

Angewandte Chemie, EarlyView.
Induced by positive electrochemical potentials, thermocatalytic hydrogenation (TCH) of 3‐nitrostyrene with H2 delivers one single product with six‐fold enhanced yield. The enhanced selectivity and activity originate from changes in the adsorption geometry of 3‐nitrostyrene and in the surface concentration of 3‐nitrostyrene and hydrogen via a concurrent

Comparison of rat hypertrophic scar models: Caudal tension model with superior pathological consistency

Animal Models and Experimental Medicine, EarlyView.
This study compared hypertrophic scar (HS) formation in SD rats at ear, back, and tail sites with or without mechanical tension. The ear model healed spontaneously by day 30. Dorsal full‐thickness excision (1 × 8 cm) produced moderate HS. In contrast, the tail tension model showed the greatest scar thickness, fibroblast density, collagen deposition ...
