Post-Functionalized Vinyl-Addition Polynorbornenes as Modular Platforms for Anion Exchange Membranes: Structure–Property Relationships

Abstract Fully hydrocarbon-based anion exchange membranes (AEMs) were developed through a facile post-polymerization strategy using vinyl-addition polynorbornene (VA-PNB) backbones. A high-molecular-weight poly(5-vinyl-2-norbornene) (PVNB) precursor was synthesized via chemoselec...

Volatile eutectics to tailor crystallization for perovskite optoelectronics

Improvements to the radiative efficiency of halide perovskite thin films are necessary to approach fundamental solar cell performance limits. We tailored perovskite crystallization by leveraging the eutectic interaction between zinc bromide and methylammonium chloride additives....

High‐Mobility Chalcogenophene‐Engineered Diketopyrrolopyrrole Mixed Ionic‐Electronic Conductors With Doping Tolerance for Low‐Power Organic Electrochemical Transistors

ABSTRACT Optimizing the steady‐state performance of organic electrochemical transistors (OECTs) requires simultaneous control over both molecular‐level design and structural ordering in organic mixed ionic–electronic conductors (OMIECs). Here, we report a series of diketopyrrolop...

A Modular and Divergent Strategy for Dibenzo[ b,f ]oxepine Natural Products: Total Syntheses of Pacharin, Bauhiniastatins 1–4, and Bauhinoxepins C–J and Structural Revision of Bauhinoxepin F

Abstract We report the development of synthetic routes to representative Bauhinia family natural products, including pacharin, bauhiniastatins 1–4, and bauhinoxepins C–J. The key transformation involves a one-pot aldol condensation/SNAr sequence to efficiently construct the diben...

Role of Mn3+/Mn4+ redox-coupled oxygen vacancy modulation in SnO2 nanoarchitectures for ultrasensitive acetone detection

Eliminating Texture‐Induced Retention of Self‐Assembled Monolayer Residues for High‐Performance Perovskite Solar Cells

Self-assembled monolayers (SAMs) constitute foundational interfacial elements in high-efficiency inverted perovskite solar cells (PSCs); however, ensuring chemical and electronic integrity across SAM-modified interfaces remains challenging. Although post-deposition solvent washin...

The Korea Chemical Bank: Over 25 years of national chemical infrastructure alongside KRICT 's 50‐year journey

Abstract Since its establishment in 2000 under the Korea Research Institute of Chemical Technology (KRICT), the Korea Chemical Bank (KCB) has evolved into the nation's largest public compound library. It serves as the official national R&D repository for chemical research outputs...

Polyolefins Derived from 5-Vinyl-2-norbornene as Platforms for Functional Polymers

Abstract 5-Vinyl-2-norbornene (VNB) is a cyclic olefin monomer containing a norbornenyl double bond and a vinyl double bond. Selective insertion of the norbornenyl double bond during the Ziegler–Natta homopolymerization and copolymerization of VNB produces polyolefins bearing pen...

Transcriptome-based classification in mice with ASD-risk mutations

Autism spectrum disorder (ASD) is a neurodevelopmental condition with a strong genetic component. Large-scale human genetic studies have identified >1200 ASD-risk genes. We report a sex-balanced atlas of 1008 prefrontal RNA sequencing (RNA-seq) profiles from 17 mouse lines carryi...

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

ABSTRACT Dark current density ( J D ) fundamentally limits the noise characteristics and detectivity of organic photodetectors (OPDs), arising primarily from reverse‐bias carrier injection and trap‐mediated leakage pathways in donor‐acceptor (D‐A) bulk‐heterojunction (BHJ) active...
