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.
