Synthesis, Surface Modification and Controlled Assembly of Porous Nanoscale Building Blocks

这个德法项目的目的是开发合成策略，用于生成结构定义的，功能化的多孔纳米晶体，这些纳米晶体将作为功能性二维和三维结构组装的构建块。来自胶体化学，分子自组装和模板概念的工具将被用于建立层次结构。在慕尼黑大学（LMU），项目合作伙伴将从胶体结构中生长出结构/形态上定义的多孔纳米级构建块，无论是通过附着在自组装单层（SAM）上然后生长，还是通过不同的图案化技术，如旋涂或微接触印刷。此外，从溶液中的功能自组装膜上的纳米多孔膜的直接定向生长将进行研究。所得到的有序结构将在应用中进行检查，如选择性化学传感器和半导体应用的介电层。在穆尔豪斯大学（LMM），合作伙伴将开发从致密水凝胶系统中形成和分离分子稳定的纳米级多孔结构单元，并通过选定的预形成晶体的分层。利用LMU团队开发的知识，构建块表面的分子功能化将成为组装三维有组织结构（如用于催化和分离应用的珠、空心球或纤维）的最终目的的工具。例如，在生成具有不同尺寸范围的分子路径的三维分层对象时，可以显著改善催化中的传质。LMU团队将研究由此产生的材料的催化应用。

This German-French project is aimed at developing synthetic strategies for the generation of structurally defined, functionalized porous nanocrystals that will serve as building blocks for the assembly of functional two- and three-dimensional constructs. Tools derived from colloid chemistry, molecular self-assembly and templating concepts will be used in concert to establish hierarchical structures. At the University of Munich (LMU), the project partners will grow structurally/morphologically defined porous nanoscale building blocks from colloidal structures, either via attachment on self-assembled monolayers (SAMs) followed by growth, or via different patterning techniques such as spin-coating or micro-contact printing. Furthermore, the direct oriented growth of nanoporous films on functional SAMs from solution will be investigated. The resulting ordered constructs will be examined in applications such as selective chemical sensors and dielectric layers for semiconductor applications. At the University of Mulhouse (LMM), the partners will develop the formation and isolation of molecularly stabilized nanoscale porous building blocks from dense hydrogel systems and via delamination of selected pre-formed crystals. Molecular functionalization of the building block surfaces, drawing on knowledge developed by the LMU-team, will be the tool for the ultimate purpose of assembling three-dimensional organized constructs such as beads, hollow spheres or fibers for catalytic and separation applications. For example, in generating three-dimensional hierarchical objects with different size-ranges of molecular pathways, mass transfer in catalysis can be significantly improved. The resulting materials will be studied for catalytic applications by the LMU-team.
