Coordinative polymers (CP) are a subclass of Metal-organic frameworks (MOFs) with porous microstructures which have been widely synthesized in recent years and applied in various fields especially in catalysis science. In this work Coordinative polymers (CP) of nickel and citric acid (CA) was prepared as a new catalyst (Ni-CP) and applied in organic multicomponent reactions. The obtained catalyst was characterized by SEM, WDX, EDS, AAS, FT-IR, XRD and BET analysis. N adsorption-desorption isotherms indicate good BET surface area for Ni-CP; therefore can be employed as an efficient catalyst in multicomponent reactions for the synthesis of polyhydroquinoline and 2,3-dihydroquinazolin-4(1H)-one derivatives. Finally, this catalyst was recovered and reused several consecutive times.

配位聚合物（CP）是金属有机框架（MOF）的一个子类，具有多孔微结构，近年来已被广泛合成并应用于各个领域，特别是在催化科学领域。在这项工作中，制备了镍与柠檬酸（CA）的配位聚合物（CP）作为一种新型催化剂（Ni-CP），并将其应用于有机多组分反应。通过扫描电子显微镜（SEM）、波长色散X射线光谱仪（WDX）、能谱仪（EDS）、原子吸收光谱仪（AAS）、傅里叶变换红外光谱仪（FT-IR）、X射线衍射仪（XRD）和比表面积分析仪（BET）对所得催化剂进行了表征。氮气吸附-脱附等温线表明Ni-CP具有良好的比表面积；因此，它可以用作合成多氢喹啉和2,3-二氢喹唑啉-4(1H)-酮衍生物的多组分反应中的高效催化剂。最后，该催化剂被回收并连续重复使用了几次。
