Self-assembly and directed assembly have been employed as very powerful methods for fabricating functional materials from nanoscale building blocks. New properties unavailable from individual nanoparticles are often created through the collective effects such as interparticle coupling and structural ordering. An important consequence of the formation of such secondary structures is that the properties of nanoparticle ensembles can be dynamically controlled by manipulating the assembly and disassembly behaviors, making them excellent candidates for constructing stimuli-responsive or smart materials. In this presentation, I will use a number of examples recently developed in my group to demonstrate that dynamic assembly and disassembly processes can be utilized as powerful tools to construct functional optical materials that can effectively respond to stimuli such as temperature, chemical environment, and electric and magnetic fields.
