A novel mesoporous composite was prepared through the hybridization of cobalt-based metal-organic framework (Co-MOF) and covalent organic framework (COF) based on melamine and terephthaldehyde (Co-MOF/COF) and characterized by FT-IR, SEM, XRD, EDS, BET, and STA analyses. The resultant composite was utilized as a robust recoverable catalyst in the condensation of several aldehydes with malononitrile to produce benzylidenemalononitrile derivatives in 62–94% yields under solvent-free conditions at room temperature using 15 mg of the catalyst and 5–60 min of reaction. The examination of catalytic performance of designated Co-MOF/COF exhibited an outstanding activity for the Knoevenagel condensation in a very short time. The recoverability, reusability and durability of Co-MOF/COF have also been investigated under applied conditions.

通过基于三聚氰胺和对苯二甲酸的钴基金属有机骨架（Co-MOF）和共价有机骨架（COF）的杂化，制备了新型介孔复合材料，并通过FT-IR，SEM， XRD，EDS，BET和STA分析。所得的复合物在几种醛与丙二腈的缩合反应中用作稳健的可回收催化剂，在室温下使用15 mg催化剂和5-60分钟的反应在无溶剂条件下以62-94％的产率生产亚苄基丙二腈衍生物。对指定的Co-MOF / COF的催化性能的检查在很短的时间内就显示出Knoevenagel缩合的出色活性。还已在应用条件下研究了Co-MOF / COF的可回收性，可重复使用性和耐久性。
