Abstract The role of N-heterocyclic carbene, a well-known reactive site, in chemical catalysis has long been studied. However, its unique binding and electron-donating properties have barely explored other research areas, such as metal capture. Herein, we report the design preparation poly(ionic liquid)-derived porous organic polycarbene adsorbent with superior gold-capturing capability. With carbene sites network “nanotrap”, it exhibits an ultrahigh gold recovery capacity 2.09 g/g. In-depth...
Abstract Gradients play a pivotal role in membrane technologies, e.g., osmotic energy conversion, desalination, biomimetic actuation, selective separation, and more. In these applications, the compositional gradients are of great relevance for successful function implementation, ranging from solvent separation to smart devices; However, construction functional gradient membranes is still challenging both scale directions. Inspired by specific function‐related, graded porous structures...
Chronical exposure to volatile acetone could damage the liver and kidney or nerve, cause inflammation. Design of novel materials for sensitive selective detection is great importance. We report on a europium (Eu)-containing covalent organic framework (DhaTab-COF-EuIL) synthesized via Schiff-base reaction between 2,5-dihydroxyterephthalaldehyde (Dha) 1,3,5-tris(4-aminophenyl)benzene (Tab) followed by an ionic liquid (IL)-modification then ion displacement. The resulting DhaTab-COF-EuIL...
Fiber-shaped supercapacitors (FSCs) are promising energy storage devices that meet the growing demands for miniaturization, flexibility, and compatibility of wearable electronics. However, when compared with batteries, low density remains main limitation to practical applications.

Conjugated microporous polymers (CMPs) are promising electrode materials for electrochemical energy storage, but their poor redox activity and electric conductivity limit practical applications. Herein, CMPs obtained from the Buchwald–Hartwig coupling reaction using a spirobifluorene bromide core p-phenylenediamine linker (SACMPs) grafted onto multiwalled carbon nanotube (MWCNT) via one-step in situ polymerization. The as-prepared composite (MWCNT@SACMP) exhibits high surface area of 514 m2...

With the rapid development of energy storage technology, operation portable and wearable devices is inseparable from high density power supplies. However, demand for performance supercapacitors in movable smart electronics still restrained by their insufficient areal capacitance limited power/energy densities. In addition, some electroactive materials, including metal oxides, conductive polymers, graphene, porous carbons, etc., are inevitable to use extra adhesives preparation electrode...
