The development of large-area two-dimensional all sp2 carbon-linked covalent organic frameworks (COFs) film still remains a challenge, because the shortage effective synthesis methods and optimal building blocks. To date, vinylene-bridged COFs synthesized by solvothermal method at high temperatures pressures are insoluble unprocessable powders, which lead to formidable challenge in fabricating thin film-based electronic optoelectronic devices. By using liquid–liquid interface polymerization...
The development of novel synthetic methodologies and unprecedented structures covalent organic framework (COF) films is great importance for exploring their potential applications in optoelectronic devices, sensors, membrane separation. From the point view monomer selection, rigid building blocks are always first choice synthesizing crystalline COF films. However, preparation with flexible units remains challenging. Herein, by introducing triphenylamine-based units, a nonplanar film...
Organic memristors as promising electronic units are attracting significant attention owing to their simplicity of molecular structure design. However, fabricating high-quality organic films via novel synthetic technologies and exploring unprecedented chemical structures achieve excellent memory performance in memristor devices highly challenging. In this work, we report a cathodic electropolymerization synthesize an ionic azulene-based memristive film (PPMAz-Py+Br–) under the...
Vinylene-linked covalent organic frameworks (COFs) are traditionally synthesized through solvothermal methods using solvents. However, the laborious process of optimizing solvent ratios and environmental harm caused by solvents constrain facile large-scale synthesis COFs. Consequently, employing water as an environmentally benign reaction medium is highly desirable for synthesizing chemically stable vinylene-linked COF materials. In this study, we report a novel self-template hydrothermal...
Abstract Organic memristors based on covalent organic frameworks (COFs) exhibit significant potential for future neuromorphic computing applications. The preparation of high‐quality COF nanosheets through appropriate structural design and building block selection is critical the enhancement memristor performance. In this study, a novel room‐temperature single‐phase method was used to synthesize Ta−Cu 3 COF, which contains two redox‐active units: trinuclear copper triphenylamine. resultant...
Abstract Ionic vinylene‐linked covalent organic frameworks (ivCOFs) with ionic characteristics and highly conjugated structures have been promising functional materials. However, both the number of reported COFs its synthetic methodologies still be limited. Herein, two new kinds (named as COF‐NUC‐1 COF‐NUC‐2) are synthesized by novel geomimetic interfacial hydrothermal synthesis for first time. Due to insolubility aldehyde monomers in water, a molecule/water interface is created, where...
The major disadvantages of MXene with abundant low-valence metal species are its poor environmental stability and solution processability. best way to address these problems is covalently functionalize highly soluble conjugated polymers, which can not only significantly enhance the solubility but also further expand application scope in optoelectronic electronic devices. By using 4-bromobenzoyl-functionalized (Ti3C2TX) as a key two-dimensional template,...
Topological defect-containing carbons (or high-entropy carbons), which are synthesized from an azulene-enriched precursor, show strong relationship between topological defects and Fe sites for oxygen reduction.
Abstract How to erase sensitive data stored on memory devices quickly in an emergency has become a critical issue that needs be addressed. Using BP‐BIBB as key template for atom transfer radical polymerization, which is prepared by the reaction of p ‐hydroxyphenyl‐functionalized black phosphorous nanosheets (C 6 H 4 OH‐BP) with 2‐bromoisobutyryl bromide (BIBB), highly soluble poly[4‐(4‐(3,3,4,4,5,5‐hexafluoro‐2‐(2‐methyl‐5‐phenylthiophen‐3‐yl)cyclopent‐1‐en‐1‐yl)‐5‐methylthiophen‐2‐yl)phenyl...

Abstract In order to improve the solubility of metallated monomers and product crystallinity, metal–covalent organic frameworks (MCOFs) are commonly prepared via high‐temperature sol‐vothermal synthesis. However, it hampers direct extraction crystallization evolution information. Exploring facile room‐temperature strategies for both synthesizing MCOFs exploiting crystallinity mechanism is extremely desired. Herein, by a novel single‐phase synthetic strategy, three with different...
