内容摘要：

Current interest in assembling inorganic nanoparticles (NPs) stems from their collective properties that may vastly differ from discrete NPs and corresponding bulk materials. Despite recent breakthroughs in NP synthesis, controlled assembly of NPs into architectures with desired complexity and functionality remains a challenge. The anchoring of polymers onto inorganic NP surfaces offers a powerful route to direct the self-assembly of NPs into defined structures with new or advanced properties that are originated from the combination features of both inorganic NP cores and tethered polymers. However, the assembly behaviors of polymer-grafted NPs are still not well understood and there remains challenging to precisely control the organization of such hybrid building blocks. In this talk, I will present our recent efforts on the self-assembly of polymer-grafted NPs as giant atoms or molecules into functional composite materials with broad applications in coating, sensing, biomedicine, metamaterials and photonic crystals.
