Luminescent coordination-driven supramolecular assemblies based on pre-organized Cu(I) precursors stabilized by main-group element ligands

考虑到从含有丰富元素的化合物（如铜）中获得廉价发光材料的不足，该ANR-DFG SUPRALUM项目旨在制备和研究一系列新的离散和聚合多金属Cu(I)基超分子组件的多功能发光特性。这些新的廉价和稳定的衍生物将呈现前所未有的结构，包括增强的固态发光特性，这将使它们成为结合照明和传感器应用的新型多功能分子材料的非常有吸引力的来源。实验和计算相结合的方法将统一对配位和超分子化学、主族元素化学、光物理和材料科学的基本理解和应用。联盟成员已经掌握的创新的配位驱动的超分子合成路线将适用于新的直接的高产量多金属Cu(I)衍生物的合成。第一次，德国和法国团队都有专门的和互补的合成工具和表征技能(例如适应柔性Cu（I)预组装前体的配位驱动超分子化学以及多晶体组装主基团（P, as, Sb， P， P， P， P， P， P， P， P， P， P， P， P， P， P， P， P， P， P， P， P）的创新使用）。为了在目标多金属超分子支架中特别引入发光特性，将结合双配体配合物和全脂肪族和柔性多面体连接物，赋予该项目显著的新颖性。最先进的光物理研究和计算将被执行，以突出发光特性，并使合成新材料中固有的电子过程合理化。因此，有可能对这种发光超分子化合物的结构-性质关系进行前所未有的深入研究，诱导发光Cu(I)衍生物家族的显着增长，以建立一种新兴的有前途的发光分子材料。德国和法国的研究小组都取得了非常令人鼓舞的初步成果，这是他们合作的基础，为该项目将产生新的科学知识和创新的环境友好型多功能发光材料提供了实质性的保证，这些材料与可持续发展密切相关。

Given the deficit of inexpensive and luminescent materials from compounds containing abundant elements as for instance copper, this ANR-DFG SUPRALUM project targets the preparation and the study of the multifunctional luminescence properties of a large series of new discrete and polymeric polymetallic Cu(I) based supramolecular assemblies. These new inexpensive and stable derivatives will present unprecedented architectures that include enhanced solid-state luminescence properties, which will establish them as a very appealing source of new multifunctional molecular materials incorporating both lighting and sensor applications. A combined experimental and computational approach will be performed that will unify the fundamental understanding and application of coordination and supramolecular chemistry, main-group elements chemistry, photophysics and material sciences. Innovative coordination-driven supramolecular synthetic routes already mastered by the consortium members will be adapted to new straightforward high-yield syntheses of polymetallic Cu(I) derivatives. For the first time, the specific and complementary synthetic tools and characterisation skills available in both the German and the French group (such as the coordination-driven supramolecular chemistry adapted to flexible Cu(I) pre-assembled precursors as well as the innovative use of polytopic assembling main group (P, As, Sb, Bi) ligand complexes and of fully aliphatic and flexible polytopic linkers) will be combined in order to specifically introduce luminescence properties within the targeted polymetallic supramolecular scaffolds, conferring a significant level of novelties to this project. State-of-the-art photophysical investigations and calculations will be executed to highlight luminescence properties and rationalise electronic processes that are inherent in the synthesised new materials. It will thus be possible to execute an unprecedentedly thorough study of the structure-property relationships of such luminescent supramolecular compounds, inducing a significant growth of the family of luminescent Cu(I) derivatives to establish an emerging and promising class of emissive molecular materials. Very encouraging first results have been obtained by both the German and French groups that are the basis of their cooperation, providing substantial guarantees that this project will generate new scientific knowledge and innovative classes of environmentally friendly, multifunctional luminescent materials that are highly relevant in the line of sustainable development. .
