Abstract

A highly stable thiazole functionalized covalent triazine framework, namely CTF-BT-500, was developed for C₂H₆/C₂H₄ separation, which exhibits a record-high ethane uptake (99.7 cm³ g⁻¹) among all reported COFs at 298 K and 1 bar. This work not only presents an excellent C₂H₆-selective adsorbent, but also provides guidance for the construction of robust adsorbents for value-added gas purification.
