分别通过点击反应和Yamamoto偶联反应合成了两种含1，2，3-三唑基的多孔有机聚合物CPP-C和CPP-Y。研究了合成方法对CPP-C和CPP-Y结构和性能的影响。它们的化学成分几乎相同，但它们的物理和质地性质彼此不同。超细钯纳米粒子可以有效地固定在CPP-C和CPP-Y的内腔中。通过红外光谱、固体核磁共振、X射线光电子能谱和能谱分析证实了聚合物与钯的相互作用。通过烯烃加氢反应评价了它们的催化性能。Pd@CPP-Y比Pd@CPP-C具有更高的催化活性和可回收性。热过滤和三相试验表明，加氢作用是以非均相途径进行的。
Two 1,2,3-triazolyl-containing porous organic polymers (CPP-C and CPP-Y) were readily synthesized through click reaction and Yamamoto coupling reaction, respectively. The effects of synthetic methods on the structures and properties of CPP-C and CPP-Y were investigated. Their chemical compositions are almost identical, but their physical and texture properties are different from each other. Ultrafine palladium nanoparticles can be effectively immobilized in the interior cavities of CPP-C and CPP-Y. The interactions between polymers and palladium are verified by IR, solid-state NMR, XPS, and EDS. Their catalytic performances are evaluated by hydrogenation of olefins. Pd@CPP-Y exhibits higher catalytic activity and recyclability than Pd@CPP-C. Hot filtration and the three-phase test indicate that hydrogenation functions in a heterogeneous pathway.
