GRK 2536: Hybrid structures on the nanoscale: Chemical concepts to prepare heterogeneous nanostructures with anisotropic material properties (NANOHYBRID)

该项目的目标是在化学制备纳米结构的基础上获得特定的各向异性材料性能，并通过具体的物理研究结合理论建模来探索新兴的材料性能。在这种强跨学科的方法中，我们将开发创新的方法，通过使用无机，大分子和理论化学的现代概念来定制纳米系统的形状和功能。此外，我们将开发纳米结构的宏观组装和定向排列技术，以证明各自的材料特性对宏观功能器件的适用性。研究项目的关键要素是半导体和金属构件，它们被组合成各向异性异质结构。同时，杂化结构将由功能分子桥接形成二维网络，或将排列在三维聚合物或无机基质中。由此产生的各向异性光学和电学特性与显示或传感器技术的应用高度相关。该研究和培训计划的一个基本特征是实验与理论之间的强烈互动，这将导致对无机杂化结构的集体性质的深刻理解。这对综合化学纳米技术的长期愿景构成了重要的科学贡献。研究生院的研究驱动型培训理念为纳米科学领域结构良好的博士课程提供了理想的条件。化学合成和物理研究的直接结合以及具有高适用性的材料特性的理论建模将导致对纳米科学和纳米技术跨学科领域的全面洞察。由化学家和物理学家组成的项目领导小组已经在汉堡大学正在进行的研究生项目“纳米科学”中紧密地联系在一起。

The goal of the Graduiertenkolleg is to achieve specific anisotropic material properties based on chemically prepared nanostructures, and to explore the emerging material properties by specific physical investigations in combination with theoretical modelling. Within this strongly interdisciplinary approach, we will develop innovative methods to tailor the shape and function of nanoscopic systems by using modern concepts of inorganic, macromolecular and theoretical chemistry. In addition, we will develop techniques for macroscopic assemblies and oriented arrangements of the nanostructures to demonstrate the applicability of the respective material properties to macroscopic functional devices. Key elements of the research projects are semiconducting and metallic building blocks, which are combined to anisotropic heterostructures. In parallel, the hybrid structures will be bridged by functional molecules to form 2-dimensional networks, or will be arranged within 3-dimensional polymeric or inorganic matrices. The resulting anisotropic optical and electrical properties are highly relevant for applications in displays or sensor technologies. An essential characteristic of the research and training program is the strong interaction between experiment and theory, which will lead to a deep understanding of the collective properties of inorganic hybrid structures. This constitutes an important scientific contribution to the long-term vision of an integrated chemical nanotechnology. The research-driven training concept of the Graduiertenkolleg offers ideal conditions for a well-structured PhD program in the field of nanoscience. The direct combination of chemical synthesis and physical investigation together with theoretical modelling of material properties with high applicability will lead to a comprehensive insight into the interdisciplinary field of nanoscience and nanotechnology. The group of project leaders consisting of chemists and physicists is already tightly intertwined within the ongoing graduate program “nanoscience” at the University of Hamburg.
