Two‐Dimensional Polymer Networks Locking on Inorganic Nanoparticles

Two‐dimensional polymers (2DPs), single‐layer networks of covalently linked monomers, show perspectives as membranes and in electronics. However, 2D polymerization of monomers in orthogonal directions limited the formation of 2DPs on nanoparticles (NPs) with high surface curvatures. Here we propose...

Description
Summary:Two‐dimensional polymers (2DPs), single‐layer networks of covalently linked monomers, show perspectives as membranes and in electronics. However, 2D polymerization of monomers in orthogonal directions limited the formation of 2DPs on nanoparticles (NPs) with high surface curvatures. Here we propose a high‐curvature 2D polymerization to form a single‐layer 2DP network as a non‐contacting ligand on the surface of NPs for their stabilization and functionalization. The high‐curvature 2D polymerization of amphiphilic Gemini monomers was conducted in situ on surfaces of NPs with various sizes, shapes, and materials, forming highly cross‐linked 2DPs. Selective etching of core–shell NPs led to 2DPs as a non‐contact ligand of yolk‐shell structures with excellent shape retention and high NP‐surface accessibility. In addition, by copolymerization, the 2DP ligands can covalently link to other functional molecules. This work promotes the development of 2DPs on NPs for their functional modification. A high‐curvature two‐dimensional (2D) polymerization is proposed to form a single‐layer 2D polymer network as a non‐contacting ligand on the surface of nanoparticles for their stabilization and functionalization. The 2D polymer network coated on nanoparticle surfaces can be turned into a non‐contact ligand showing excellent shape retention and high nanoparticle‐surface accessibility.
