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 lit, 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.
