The design and synthesis of 3D covalent organic frameworks (COFs) have been considered a challenge, and the demonstrated applications of 3D COFs have so far been limited to gas adsorption. Herein we describe the design and synthesis of two new 3D microporous base‐functionalized COFs, termed BF‐COF‐1 and BF‐COF‐2, by the use of a tetrahedral alkyl amine, 1,3,5,7‐tetraaminoadamantane (TAA), combined
3D共价有机骨架(COF)的设计和合成已被认为是一项挑战,迄今为止,已证明的3D COF的应用仅限于气体吸附。本文中,我们通过使用四面体烷基胺1,3,5,7-四氨基金刚烷(TAA)来设计和合成两种新的3D微孔碱功能化COF,称为BF-COF-1和BF-COF-2。 ),与1,3,5-三甲酰苯(TFB)或三甲酰间苯三酚(TFP)结合使用。作为催化剂,两种BF-COF均表现出显着的转化率(BF-COF-1的转化率为96%,BF-COF-2的转化率为98%),高尺寸选择性以及在碱催化的Knoevenagel缩合反应中良好的可回收性。这项研究表明,多孔功能化3D COF可能是一类有前途的新型形状选择催化剂。
