Focus of this project is developing a new concept for the formation of self-assembled hierarchically structured organic-inorganic nanoparticles in aqueous solution. First, macroions, multivalent ionic dye molecules and metal ions are associated in aqueous solution and subsequently the metal ions are transformed into metal or semiconductor nanoparticles through a chemical reaction. In this, the supramolecular structure influences size and morphology of the particles built. New ternary hybrid assemblies consisting of macroions, dyes and inorganic material result. Nanoscale assemblies will in detail be structurally characterized by light and small angle scattering, atomic force microscopy, electron microscopy and UV-vis spectroscopy. In addition, thermodynamics and kinetics of the structure formation will be investigated to elucidate the relationship between building block structure, intermolecular interaction and particle shape and size. Novel supramolecular organic-inorganic hybrid structures can be of importance in nanotechnology, switchable optical materials and in catalysis.

该项目的重点是开发一种在水溶液中形成自组装分层结构有机-无机纳米颗粒的新概念。首先，大离子、多价离子染料分子和金属离子在水溶液中缔合，随后金属离子通过化学反应转化为金属或半导体纳米颗粒。其中，超分子结构影响所构建颗粒的尺寸和形态。由大离子、​​染料和无机材料组成的新型三元杂化组件。纳米级组件将通过光和小角散射、原子力显微镜、电子显微镜和紫外可见光谱来详细表征结构。此外，还将研究结构形成的热力学和动力学，以阐明积木结构、分子间相互作用以及颗粒形状和尺寸之间的关系。新型超分子有机-无机杂化结构在纳米技术、可切换光学材料和催化领域具有重要意义。
