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.
