The present invention provides a template-directed self-assembly strategy to integrate the class of materials called dendrimers with periodic mesoporous and macroporous silica materials to create two totally new classes of organic/inorganic nanocomposite materials, which we call periodic mesoporous dendrisilicas (PMeDs) and periodic macroporous dendrisilicas (PMaDs). The unusual combination of inorganic silica and organic dendrimer chemical structures with these scales of porosity and surfaces suggests a myriad of uses for PMeDs and PMaDs, such as the controlled release and uptake of chemicals, chiral separations and catalysis, electronic printing and microelectronic packaging, biomaterial platforms, chromatography stationary phase, and photonic crystal applications. These applications target the synergistic relationship between the dendrimer and the meso- or macroporous structure within a single hierarchical nanostructured organic/inorganic hybrid material.
本发明提供了一种模板导向的自组装策略,将一类名为树状分子(dendrimers)的材料与周期性介孔和大孔
硅材料集成,从而创造出两种全新的有机/无机纳米复合材料类别,我们称之为周期性介孔树状

硅材料(PMaDs)。无机
硅和有机树状分子
化学结构在这些孔隙和表面尺度上的不寻常组合,为PMeDs和PMaDs提供了多种用途,如
化学品的控制释放和吸收,手性分离和催化,电子印刷和微电子封装,
生物材料平台,色谱柱固定相以及光子晶体应用。这些应用针对的是树状分子与单一分级纳米结构有机/无机混合材料中的介孔或大孔结构之间的协同关系。
