Porous organic polymers (POPs) are promising supporters for transition metal-catalyzed reactions owing to high specific surface area, good chemical stability and modular synthesis. Controllable synthesis of POPs-supported nanoparticles is of great significance for developing efficient heterogeneous catalysis and broadening the application scope of POPs. 

Prof. WANG Ruihu’s research group at Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, has reported a new strategy for facile fabrication of ultrafine palladium nanoparticles (NPs) with size- and location-control in the interior cavities of porous organic polymers. 

A series of click-based POPs were synthesized by simple click reactions. Through the synergistic effects of the coordination of 1,2,3-triazolyl to palladium and the confinement effect of polymers, in combination with the fine adjustment of synthetic methods, controllable synthesis of ultrafine palladium NPs in POPs is achieved. The catalytic systems have demonstrated high catalytic activity, superior selectivity and good recyclability in hydrogenation of nitro-containing compounds.  

The study provides experimental and theoretical basis for the controllable synthesis of nanoparticles and tunable catalytic performance. Results of this study have been published as an article in ACS Nano, 2014, 8, 5352-5364.
