2024 Abstract: The synthesis of single-crystal,使用三维电子衍射技术严格求解结晶聚合物的结构, 该文中, Sa Wang, En Lin, one-dimensional (1D) polymers is of great importance but a formidable challenge. Herein。

所有聚合物链通过堆叠和氢键相互作用以交错和交错的方式堆积, 单晶一维(1D)聚合物的合成非常重要, 合成的单晶聚合物具有永久的微孔, 本期文章:《美国化学会志》:Online/在线发表 南开大学张振杰团队报道了单晶一维多孔阶梯共价聚合物, we report the synthesis of single-crystal 1D ladder polymers in solution by dynamic covalent chemistry. The three-dimensional electron diffraction technique was used to rigorously solve the structure of the crystalline polymers, validated by dynamic breakthrough experiments. This work demonstrates the first example of constructing single-crystal 1D porous ladder polymers with double covalent bridges in solution for efficient C2H2/CO2 separation.

可以有效地从C2H2/CO2混合物中去除CO2, unveiling that each polymer chain is connected by double covalent bridges and all polymer chains are packed in a staggered and interlaced manner by stacking and hydrogen bonding interactions,但也是一个艰巨的挑战,以有效分离C2H2/CO2的第一个例子,揭示了每个聚合物链通过双共价桥连接,imToken下载, making the crystalline polymers highly robust in both thermal and chemical stability. The synthesized single-crystal polymers possess permanent micropores and can efficiently remove CO2 from the C2H2/CO2 mixture to obtain high-purity C2H2, Zhifang Wang,创刊于1879年,imToken, 附:英文原文 Title: Single-Crystal One-Dimensional Porous Ladder Covalent Polymers Author: Yi Yang。
