Discrete nanostructures have a limited scope of applications, due to potential cytotoxicity and difficulty in separation and recovery after use. Furthermore, a functional nanostructure nowadays is normally not a single-phase solid, but a highly organized multicomponent materials system. To prepare such complex nanomaterials, architectural aspects of design and synthesis need to be addressed, because the ways of compositional and structural organizations in the final products will give profound impacts on their ultimate performance. Therefore, our recent research efforts are mostly directed to development of chemical methods for integrative organization of functional materials into complex nanostructures, which will be the subject of this presentation. We have recently synthesized a range of functional nanostructures with architectural designs. In particular, chemical and structural transformations were often employed in our processing steps in liquid media under mild reaction conditions.1-5 Similar to organic synthesis, for example, various molecular modifications of solid surfaces were utilized in our synthetic processes in order to create steric hindrance effects, binding interactions, and control of surface reactivity for directional growth and organization of nanomaterials.1-5 To make composite nanostructures usable in real reaction environments, for instance, new synthetic strategies for multicomponent nanomaterials with permanent engagement among primary building units have been developed. Tiered integrations among different components have also been addressed in several model systems, including architecture of porosity and interior space.1. H. C. Zeng, Acc. Chem.
