Developing novel synthetic strategies to construct crystalline polymeric materials with excellent chemical stability and high carbon capture capacity has become a challenging process. Herein, we report the synthesis of two novel 2D benzobisoxazole-linked covalent organic frameworks (BBO-COFs) utilizing C-symmetric formyl- and C-symmetric -aminophenol-substituted molecular building blocks. The BBO-COFs exhibit excellent water stability, high surface areas, and great CO uptake capacities. This general synthetic method affords the opportunity to prepare ordered BBO-based polymeric materials for carbon capture, chemical sensing, and organic electronic applications.
开发新颖的合成策略以构建具有优异化学稳定性和高碳捕获能力的结晶聚合物材料已成为一个具有挑战性的过程。在此，我们报道了利用C对称甲酰基和C对称氨基苯酚取代的分子构建块合成两种新型二维苯并双恶唑连接的共价有机框架（BBO-COF）。这些BBO-COF表现出优异的水稳定性、高比表面积和出色的CO吸收能力。这种通用的合成方法为制备用于碳捕获、化学传感和有机电子应用的有序BBO基聚合物材料提供了机会。
