Rational design of molecular architectures is crucial for developing advanced materials such as covalent-organic frameworks (COFs) with excellent sensing performance. In this work, two isostructural COFs (β-keto-AnCOF and imine-AnCOF) the same conjugated linkers but distinct linkages are constructed. Although both have porous structure semiconductor behavior conferred by identical backbones, β-keto-AnCOF ─C═O side groups exhibits superior room-temperature ammonia (NH3) performance than...
Low membrane conductivity originated from a high thickness has long been the "Achilles heel" of conventional polymeric membrane, greatly hampering improvement output power density in osmotic generation. Herein, we demonstrate molecularly-thin two-dimensional (2D) covalent organic framework (COF) monolayer featured with ultimate thickness, pore density, and tight size distribution, which performs as highly efficient generator. Despite large up to 3.8 nm relatively low surface charge 2.2 mC...
Ion transport through nanoconfinement, driven by both electrical and mechanical forces, has drawn ever-increasing attention, due to its high similarity stress-sensitive ion channels in biological systems. Previous studies have reported only pressure-induced enhancement conductance low-permeable systems such as nanotubes, nanoslits, or single nanopores. This is generally explained the accumulation caused capacitive effect Here, we fabricate a highly permeable COF monolayer membrane...
Extracting osmotic energy from waste organic solutions via reverse electrodialysis represents a promising approach to reuse such industrial wastes and helps mitigate the ever-growing needs. Herein, molecularly thin membrane of covalent frameworks is engineered interfacial polymerization investigate its ion transport behavior in solutions. Interestingly, significant deviation linearity between conductance reciprocal viscosity observed, attributed nanoscale confinement effect on intermolecular...
Abstract In recent years, with the development of interfacial polymerization methodologies, successful preparation covalent organic framework (COF) monolayers featuring ultrahigh pore density and molecule-scale thickness has become a reality. This advancement enabled ion transport flux across extremely short paths. Owing to these processes, COF have shown wide potential applications ranging from energy conversion artificial mechanosensing sieving. To date, nanofluidic systems based on are...
Exploration and construction of novel π-conjugated organic semiconductors with low cost, small background interference, excellent performance as surface-enhanced Raman scattering (SERS) substrates is one the current focuses for development SERS technology. Based on precise control over synthesis conditions, a series large-area tetraphenylporphyrin-based 2D covalent-organic framework membranes (2D-porphyrin-COFs) high uniformity precisely controllable thickness are constructed substrates. The...
Abstract Nanopore‐based power generation represents an efficient way for harvesting salinity gradient energy. Due to its ultrahigh ion conductivity and moderate selectivity, the crystalline covalent organic framework (COF) monolayer demonstrates record‐high output density by mixing river water seawater. To further improve energy conversion performance, it is necessary enhance selectivity while achieving high membrane permeability. Here, a layer‐by‐layer stacking approach developed notably...
To clarify the interactions between holocellulose and lignin, hydrolysis behaviors of sawdust, holocellulose, holocellulose–lignin mixture (HLM) in subcritical water were investigated present study, where HLM acted as a model sawdust without covalent linkages lignin. Holocellulose showed negligible effects on lignin at low reaction temperatures, whereas it might promote higher temperatures. In contrast, was inhibited by due to high bond dissociation energies them. The destruction mainly...
