摘要
Recently B←N organic frameworks (BNFs) have gained substantial attention owing to their unique dative bond energy, which imparts them with specialized functionalities across a broad spectrum of applications. Despite previous reports on BNFs with permanent porosity, research endeavors towards three-dimensional (3D) BNFs with similar properties are scarce, with no report of robust 3D BNFs featuring permanent porosity to date. Herein, electrostatic complementary strategy is proposed to construct the first example of 3D robust and microporous BNF, BNF-100, featuring a reo topology with 8-connected sandwich nodes assembled via dative B←N bonds. The activated form BNF-100 a exhibits excellent chemical stability and permanent porosity with Langmuir surface area of 645.9 m
