The direct assembly of optical nanomaterials into ordered mesoporous frameworks has proven to be a considerable challenge over the past two decades[1-7]. Herein, we propose the incorporation of ultrasmall(sub-5 nm) graphitic pencil nanodots(PNDs) into ordered mesoporous frameworks for the fabrication of optoelectronic materials. The nanodots, prepared from typical commercial graphite pencils by an electrochemical tailoring process, combine properties such as uniform size(～ 3 nm), excellent dispersibility, and high photoconversion efficiency(～ 27%). These were incorporated into a variety of ordered mesoporous frameworks(TiO, silica, carbon and silica-carbon materials) by hydrogen-bonding-driven co-assembly with the frameworks’ precursors. The resulting materials showed a high degree of ordering, and a sharp increase in their optical performance(for example photocurrent density). We envisage that the large-scale synthesis of ultrasmall carbon nanodots, and their incorporation into ordered mesoporous frameworks, may facilitate the preparation of materials with a variety of optical properties.

The direct assembly of functional materials into ordered mesostructured frameworks has proven to be a considerable challenge over the past two decades. Herein, we propose a generalized, super-assembly approach for direct fabrication of a series of ultrasmall(sub-5 nm) functional components into ordered mesostructures, referred as super-assembled frameworks(SAFs). Diverse functional unites, including nanodots, proteins, peptides, DNA and biomolecules were incorporated into a variety of ordered mesoporous frameworks(TiO, silica, carbon,

The rational design and precise synthesis of multifunctional hybrid nanostructures with a tailored active core and a large, dendritic, modified mesoporous structured shell can promote catalysis, energy storage, and biological applications. Here, an oil-water biphase stratification coating strategy has been developed to prepare monodisperse magnetic dendritic mesoporous silica core-shell structured nano- spheres. These sophisticated Fe3O4@SiO2@dendritic-mSiO2 nanospheres feature large dendritic open pores （2.7 and 10.3 nm）. Significantly, the silica shells can be converted into dendritic mesoporous aluminosilicate frameworks with unchanged porosity, a Si/Al molar ratio of 14, and remarkably strong acidic sites, through a post-synthesis approach. In addition, the resultant magnetic dendritic mesoporous aluminosilicate nanospheres exhibit outstanding properties and promising application in phosphate removal from wastewater.
