Abstract

Poly(arylene ether)s (PAEs) are a versatile class of thermoplastic materials with commercial importance. Currently their synthesis relies predominantly on either nucleophilic or electrophilic aromatic substitution reactions, severely limiting the scope of available PAEs. Herein, we report the copper(II)-catalyzed polycondensation of electronically unactivated aryl bromides with bisphenols to afford a wide range of new PAEs. These PAEs are characterized by their thermal and mechanical properties. Functional PAEs were produced that have reversible acid- and redox-triggered chromophores incorporated into the backbone, which illustrates the utility of these methods.

通过 Cu(II)催化的聚芳基醚。

聚芳基醚（PAEs）是一类用途广泛的热塑性材料，具有重要的商业价值。目前，它们的合成主要依赖于亲核或亲电芳香取代反应，这严重限制了现有 PAE 的范围。在此，我们报告了铜(II)催化的电子未活化芳基溴与双酚的缩聚反应，从而得到了多种新型 PAE。这些 PAE 的特点是具有热性能和机械性能。生产出的功能性 PAE 在骨架中加入了可逆的酸和氧化还原触发的发色团，这说明了这些方法的实用性。

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.
