A 2D covalent organic framework (COF) with ultramicroporous structure and paired functionalities is designed and synthesized. This COF is exfoliated into large-aspect-ratio nanosheets, enabling the fabrication of compatible hybrid membranes. The COF membranes exhibit superior acetylene/ethylene separation with high selectivity and large permeability owing to collaborative acetylene recognition and gas-transport highways.

用于膜 C2H2/C2H4 分离的具有功能对的超微孔共价有机骨架纳米片

设计并合成了具有超微孔结构和成对功能的二维共价有机骨架 (COF)。这种 COF 被剥离成大纵横比的纳米片，从而能够制造相容的混合膜。由于协同乙炔识别和气体传输高速公路，COF 膜表现出优异的乙炔/乙烯分离，具有高选择性和大渗透性。
