Hierarchic Nanostructures from Layer-by- Layer and Mesoporous Technologies: Fabrication and Application

摘要

Design, synthesis, and fabrication of organic materials and organic/inorganic hybrids with nano-sized structural features have to be done based on bottom-up approaches from unit molecular structures. Our group has developed novel supramolecular materials in nano, micro, and bulk dimensions. Construction of nanostructures was demonstrated by formation of two-dimensional arrays of fullerene and porphyrins. Various microscopic morphologies were successfully constructed through self-assembled process from alkyl-substituted fullerene as a shape-shifter, which also provided bulk liquid material. Structure transcription of molecular assembly resulted in well- structured bulk materials such as novel nanocarbon materials “carbon nanocage”, which exhibited unique material separation properties. In addition, approaches bridging molecular and bulk worlds based on dynamic molecular recognition have been also developed. Here, a novel hierarchic nanostructure based on layer-by-layer (LbL) assembly and mesoporous technology, so-called “mesoporous nanocompartment film (Figure 1)”, is reported.
