Abstract

Developing new materials for anhydrous proton conduction under high‐temperature conditions is significant and challenging. Herein, we create a series of highly crystalline covalent organic frameworks (COFs) via a pore engineering approach. We simultaneously engineer the pore geometry (generating concave dodecagonal nanopores) and pore surface (installing multiple functional groups such as −C=N−, −OH, −N=N− and −CF3) to improve the utilization efficiency and host–guest interaction of proton carriers, hence benefiting the enhancement of anhydrous proton conduction. Upon loading with H3PO4, COFs can realize a proton conductivity of 2.33×10−2 S cm−1 under anhydrous conditions, among the highest values of all COF materials. These materials demonstrate good stability and maintain high proton conductivity over a wide temperature range (80–160 °C). This work paves a new way for designing COFs for anhydrous proton conduction applications, which shows great potential as high‐temperature proton exchange membranes. [ABSTRACT FROM AUTHOR]

Abstract

Two C 2 H 6 -selective metal-organic framework (MOF) adsorbents with ultrahigh stability, high surface areas, and suitable pore size have been designed and synthesized for one-step separation of ethane/ethylene (C 2 H 6 /C 2 H 4 ) under humid conditions to produce polymer-grade pure C 2 H 4 . Experimental results reveal that these two MOFs not only adsorb a high amount of C 2 H 6 but also display good C 2 H 6 /C 2 H 4 selectivity verified by fixed bed column breakthrough experiments. Most importantly, the good water stability and hydrophobic pore environments make these two MOFs capable of efficiently separating C 2 H 6 /C 2 H 4 under humid conditions, exhibiting the benchmark performance among all reported adsorbents for separation of C 2 H 6 /C 2 H 4 under humid conditions. Moreover, the affinity sites and their static adsorption energies were successfully revealed by single crystal data and computation studies. Adsorbents described in this work can be used to address major chemical industrial challenges., (© 2022 Wiley-VCH GmbH.)
