Abstract

Organoboron chemistry has been widely explored and developed in synthetic chemistry for over half a century and provides various elegant synthetic protocols in polymer synthesis. Compared with most trivalent bare organoboron compounds, N-coordinated organoboron shows better performances, such as air and moisture stability. This review summarizes the application of various N-coordinated boranes and boronic acid/esters in polymer synthesis and materials science. We introduce the significance of N-coordinated boranes and boronate esters for controllable polymer synthesis and systematically summarize the structures and properties of polymers containing N-coordinated boronate esters. Furthermore, we highlight the effect of N→B dative bonds on improving the performance of self-healing materials. We hope that, through this review, more researchers will realize the advantages of N-coordinated organoboron and promote the development of this direction in polymer synthesis and materials science.

摘要

半个多世纪以来，有机硼化学在合成化学中得到了广泛的探索和发展，并在聚合物合成中提供了各种优雅的合成方案。与大多数三价裸有机硼化合物相比，N-配位有机硼表现出更好的性能，如空气和水分稳定性。本文综述了各种N-配位硼烷和硼酸/酯在聚合物合成和材料科学中的应用。我们介绍了N-配位硼烷和硼酸酯在可控聚合物合成中的意义，并系统总结了含N-配位硼酸酯的聚合物的结构和性能。此外，我们强调了N→B dative bonds用于改善自愈材料的性能。我们希望，通过这篇综述，更多的研究人员将认识到N配位有机硼的优势，并推动这一方向在聚合物合成和材料科学中的发展。
