Hollow Porous Organic Nanospheres for Anchoring Pd(PPh3)4 through Co-hyper-crosslinking Mediated self-assembly strategy

Abstract

In this work, we present a facile method for anchoring of transition metal catalyst (Pd(PPh3)4) into hollow porous organic nanospheres (H-PONs) based on co-hyper-crosslinking mediated self-assembly strategy by using polylactide-b-polystyrene (PLA-b-PS) and Pd(PPh3)4 as precursors. The intrinsic catalytic activity of Pd(PPh3)4 could be well retained even if immobilized into H-PONs through one-step Scholl reaction. Owing to the hierarchically porous structure, high surface area and well-dispersed active sites, the resulting H-PONs-Pd(PPh3)4 exhibited excellent catalytic activity, enhanced stability, and good recyclability for the Suzuki-Miyaura couplings in aqueous media. We hope that such facile synthesis approach can provide a broad platform to support various transition metal catalysts into hollow porous nanomaterials for heterogeneous catalysis field
