摘要

通过单手螺旋通道实现了外消旋螺旋低聚乙炔的螺旋感应选择性渗透（HSSPerm）。单手螺旋通道是通过相应外消旋螺旋聚乙炔膜的螺旋感应选择性分解（HSS-SCAT）在单手螺旋聚乙炔膜中形成的，然后去除形成的低聚物。由于 HSS-SCAT 反应仅在圆偏振可见光下进行，无需试剂、催化剂、溶剂和高选择性，因此很容易获得高纯度的含手性通道膜。这种膜能以高达 30%ee 的对映选择性分离外消旋螺旋低聚乙炔。据我们所知，这是 HSSPerm 的第一个实例。

Helix-Sense-Selective Permeation of Racemic Helical Oligoacetylenes through One-Handed Helical Channels in Polymer Membranes

Helix-sense-selective permeation (HSSPerm) of racemic helical oligoacetylenes through one-handed helical channels has been realized. The one-handed helical channels were created in the one-handed helical polyacetylene membranes by the helix-sense-selective decomposition (HSS-SCAT) of the corresponding racemic helical polyacetylene membranes, followed by removing the formed oligomers. Since the HSS-SCAT reaction proceeds with just circularly polarized visible light with no reagents, no catalysts, no solvent, and high selectivity, the chiral channel-containing membrane with high purity was obtained easily. This membrane could separate racemic helical oligoacetylenes enantioselectively in up to 30%ee. To our knowledge, this is the first example of HSSPerm.

期刊介绍： ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
