Acidic Electron Acceptors in Imine‐Linked Covalent Organic Framework for Enhanced Gas Sensing With Field‐Effect Transistor Evaluation

Q Z Liu, Xiansong Shi, Haofei Zheng, Mingxi Chen et autres

ABSTRACT Semiconducting covalent organic frameworks (COFs) that combine structural order with porous characteristics are promising candidates for chemiresistive sensors. Understanding carrier transport behavior and improving their electrical properties remain critical challenges due to the low intrinsic conductivity of semiconducting COFs and the …

Triphenylene-Derived Polyimide Covalent Organic Frameworks for Efficient Photosynthesis of Hydrogen Peroxide

Wei Zhao, Zhihua Li, Guanhua Ren, Jing Qi et autres

Photocatalytic hydrogen peroxide (H 2 O 2 ) production offers a sustainable route for on-demand generation. Covalent organic frameworks (COFs) are attractive candidates, as their modular architectures can be engineered for optimal light capture and charge separation. However, their practical use has …

Developmental DVE-1 programs ACT-5–dependent microvillar organization to preserve intestinal homeostasis in C. elegans

Liuqingqing Yang, Jiahui Liu, Shuqi Guo, Lihua Sun et autres

The intestinal epithelium balances nutrient absorption and barrier defense using its apical brush border. Disrupting this structure causes malabsorption and disease, but the transcriptional programs driving its formation remain unclear. Here, we identify DVE-1—a homeobox transcription factor known for regulating the mitochondrial …

In Situ Photopolymerization of Hydrogels in Radical Covalent Organic Frameworks

Wei Juan Zhao, Peiyao Yan, Xinyu Dong, Binting Huang et autres

Molecular initiating agents, particularly those used for photoinitiation, have dominated hydrogel synthesis for decades. However, their small molecular nature leads to several issues in hydrogels: migration out of the polymer matrix, poor photostability, limited functionality, and relatively poor mechanical properties. In this …

Guest-Mediated Defect Healing in Layered Metal Chalcogenides for Humidity-Resilient NO 2 Sensing

Wenhua Li, Yuanyuan Wang, Chunqing Ji, Guoming Lin et autres

Precise defect control is pivotal for advancing nanomaterial performance, yet layered metal chalcogenides are plagued by coupled, multidimensional defects that degrade their electronic, optical, and chemical functions. Here, we introduce a guest-mediated defect healing (GMDH) strategy that concurrently heals multidimensional defects in …

Stabilizing Covalent Organic Frameworks through Hydrogen Bonding Bridges for Polyamine Entanglement toward Carbon Capture from Point-Source Emissions

He Li, Xiansong Shi, Zekun Wang, Jiayi Wu et autres

Incorporating polyamine into covalent organic frameworks (COFs) is a promising strategy for developing carbon capture adsorbents with fast mass transfer, in which avoiding crystallinity and porosity loss of COFs becomes essential. Herein, we propose a hydrogen bonding (HB) bridge strategy to stabilize …

Bismuth‐Organic Framework Anodes for Extremely High Capacity and Stable Lithium Storage

Bing Zhu, Zekun Wang, Yaning Du, Yicen Liu et autres

ABSTRACT Metal–organic frameworks (MOFs) hold significant promise as anode materials for high‐performance lithium‐ion batteries (LIBs) because of their tunable structures, designable components, and intrinsic porosity. However, the practical application of many MOFs is limited by their low theoretical capacity and poor conductivity, …

Confined Water in Metal-Doped Covalent Organic Frameworks for Enhanced Physisorptive Carbon Capture under Wet Conditions

He Li, Yifan Xu, Jingcong Hu, Dohyun Ahn et autres

Unlike amine-based CO 2 chemisorption, where water can enhance amine utilization efficiency, physisorptive CO 2 capture is typically impeded by water owing to its large dipole moment and competitive adsorption behavior. Converting water into additional adsorptive sites for CO 2 adsorption in …

Control of temporal and spatial proximity effects in two-photon lithography

Leila Mehrvar, Zhu Wei, Zekun Wang, Darian Modasi et autres

Two-photon lithography (TPL) enables the fabrication of high-resolution three-dimensional (3D) nanostructures, but its precision is often limited by proximity effects, leading to feature broadening and filamentary defects, both of which can depend on the timing between adjacent feature writing. This work experimentally …
