Chalcogenidometallate Organic Hybrid Compounds Networks

项目摘要

Inorganic-organic hybrid compounds and networks that comprise complex inorganic building units, such as chalcogenidometallate clusters, are considered valuable extensions of the classical metalorganic hybrid compounds and networks, since the inorganic part strongly affects the physico-chemical properties of the respective phases. Based on the large success of the previous project DE-758/11-1, that gave rise to 14 publications in reputable journals, we would like to continue and extend our investigations on functionalized binary and ternary chalcogenidometallate-organic hybrid compounds and networks, thereby focusing on two selected areas: A) decoration of the chalcogenidometallate-organic hybrid compounds with N donor chelating ligands for (redox-active) transition metal ion sequestration; B) directed formation of chalcogenidometallate-organic networks via 2, 3, or 4-fold covalent organic linkage or via coordination of additional metal ions. For this, the variety of the organic functionalities on the surfaces of binary R*T/E cages (R* = functionalized organic group, T/E = group 14/16 elements) will be further varied to enhance the variety of subsequent reactions. The incorporation of ternary M/R*T/E clusters (M = transition metal) into the hybrid compounds will be approached following different ways. Formation pathways, stabilities, as well as chemical and physical properties of all reaction products will be explored by application of all available experimental methods and by means of quantum chemical studies. Besides characterization of the novel compounds, this shall serve to judge on their reactivity regarding molecular trapping, bond activation and redox properties. The combination of high-sophisticated syntheses with multi-faceted analyses has proved of value in the past and will therefore be likely to work finely at the continuation and extension of the project.

包含复杂无机结构单元（例如硫属金属酸盐簇）的无机-有机杂化化合物和网络被认为是经典金属有机杂化化合物和网络的有价值的扩展，因为无机部分强烈影响各个相的物理化学性质。基于先前项目 DE-758/11-1 的巨大成功，该项目在知名期刊上发表了 14 篇论文，我们希望继续并扩展对功能化二元和三元硫族金属盐-有机杂化化合物和网络的研究，从而重点关注两个选定领域：A) 用 N 供体螯合配体修饰硫族金属盐-有机杂化化合物，用于（氧化还原活性）过渡金属离子螯合； B)通过2、3或4重共价有机键或通过额外金属离子的配位直接形成硫族金属化物有机网络。为此，二元R*T/E笼表面上有机官能团的多样性（R*=官能化有机基团，T/E=14/16族元素）将进一步变化，以增强后续反应的多样性。将按照不同的方式将三元 M/R*T/E 簇（M = 过渡金属）纳入杂化化合物中。将通过应用所有可用的实验方法和量子化学研究来探索所有反应产物的形成途径、稳定性以及化学和物理性质。除了新型化合物的表征之外，这还有助于判断它们在分子捕获、键活化和氧化还原性质方面的反应性。高度复杂的综合与多方面分析的结合在过去已被证明是有价值的，因此很可能在项目的延续和扩展中发挥良好作用。
