  Recently, one paper titled as “Boronic Ester Based Vitrimers with Enhanced Stability via Internal Boron-Nitrogen Coordination” was published online in Journal of the American Chemical Society, which co-authored by Xiaoting Zhang, Shujuan Wang, Zikang Jiang, Yu Li, and Xinli Jing.

The application of the polymers containing boronic ester or boroxine linkages is limited due to their instability to water. In this paper, based on the principle that the nitrogen-donor compounds can “lock” the vacant orbital of the boron atom to stabilize the boronic ester linkages, a new strategy for improving the stability of boronic ester based vitrimers via internal boron-nitrogen coordination was proposed. We anticipate that this study will provide a novel chemical strategy and concept for designing a range of robust and stable vitrimers with the potential for commercial industrial applications.

日前,RGFP的一篇论文在ACS旗下的学术期刊Journal of the American Chemical Society上在线出版,论文题目为“Boronic Ester Based Vitrimers with Enhanced Stability via Internal Boron-Nitrogen Coordination”。论文的作者为张晓婷(博士生)、王淑娟副教授、蒋子康(硕士生)、李瑜副教授和井新利教授。

本论文针对硼酸酯基动态交联高分子耐水性不足的问题,利用胺类化合物锁定硼原子的空轨道以提高硼酸酯基稳定性的原理,提出了利用B-N内配位提高硼酸酯基Vitrimers稳定性的新策略。这项研究工作为设计具有实用价值的可持续材料提供了一个新的化学策略和概念。(撰稿:王  镇;校对:行小龙)
