报告一：Multinary Clusters: Atomically Precise Nanoobjects with Uncommon Properties
报告人：Prof. Stefanie Dehnen, Karlsruhe Institute of Technology
报告摘要：The properties of materials based on cluster compounds is largely affected by the diverse compositions and uncommon structural motifs of these nanoobjects, which result in functionalities with great potential for practical use.[1-5] We control the elemental composition by starting out from p-block element precursors that are reacted with further metal complexes or organic compounds. Depending on the chosen elemental combination, the products represent clusters of the metallide or metalate type. Some of the molecular architectures remain unsubstituted, like [K2Zn20Bi16]6– [5] or [An@Bi12]q– (An/q = U/3, Th/4),[6,7] and serve to understand fundamental aspects like electronic properties, cluster formation, and bonding. The aggregation of cluster molecules, such as in [Cs@Ge4(Ge4Se10)4]7–,[8] and the presence of of organic substituents,[10-14] like in [{CpRu}3Bi6]–,[11] [{(Me3Si)2NZn}2Bi6]2–,[12] [{(IMes)Co}2Bi5],[13] or [Sn10O4S16(SBu)4]4–,[14] additionally influence the chemical and physical properties. This leads to unique features, like extreme nonlinear optical response found in materials based on [(StySn)4S6] and related clusters.[15]
Multinary clusters without or with organic functionalization: [Th@Bi12]4–, [Sn10O4S16(SBu)4]4–, and [(PhSn)4S6].

报告摘要：Separating actinides from lanthanides is essential for managing nuclear waste and promoting sustainable nuclear energy development. In 2014, we reported a phenanthroline-based tetradentate ligand with hard–soft donors combined in the same molecule, N,N′-diethyl-N,N′-ditolyl-2,9-diamide-1,10-phenanthroline (Et-Tol-DAPhen), for the group separation of actinides over lanthanides. The ligand exhibits excellent extraction ability and high selectivity toward hexavalent, tetravalent, and trivalent actinides over lanthanides in highly acidic solution and hence renders huge potential opportunities in high-level liquid waste (HLLW) partitioning. Recently, based on the DAPhen ligand, we proposed a dual strategy to designing covalent organic frameworks (COFs) that skillfully combines molecular rigidity with flexibility, integrating both hard and soft donor atoms in the synthesis of monomers, which results in a specialized COF that efficiently and selectively captures TRUs from acidic aqueous solutions. By utilizing the topological arrangement of rigid ligands to influence the twisting and stretching of flexible ligands, coordination environment featuring nitrogen and oxygen is created, which enhances the separation of transuranium in various oxidation states over lanthanides. In 0.5 m HNO3 solution, the as-synthesized DAPhen-COF achieves removal rates of 99.1% for Np(V) and 95.8% for Pu(IV). For Am(III), the removal rate reaches 98.6% in 0.01 m HNO3. DAPhen-COF exhibits remarkable selectivity for Np(V), with a separation factor of over 5000 for Np/Gd, outperforming other solid-phase materials.
On the other hand, traditional solvent extraction and separation of actinide elements generally relies on specific organic ligands. Through the selective complexation of these ligands with the target actinide metal ions, their efficient separation in a mixture of metal ions can be achieved. The separation selectivity mainly depends on the degree of pre-organization of the ligand structure and the complexation between soft/hard complexing atoms and the target ions. Based on years of research on actinide coordination supramolecules, we proposed a new paradigm for the separation of actinide elements (actinide nano-extraction) by using coordinated assembly of nanoclusters as the extracted species state. That is, using macrocyclic pyrogallol[4]arene as an extractant, it captures and chelates uranyl ions at the water phase/organic phase interface and in-situ assembles to form a uranyl coordination nanocage, realizing the efficient extraction and separation of uranyl ions. Studies have shown that each coordination nanocage is assembled from 6 pyrogallol[4]arene macrocycles and 24 uranyl ions. Multiple components exhibit multivalent cooperativity during the assembly process, which can achieve high selectivity and efficiency for uranyl ions. This new idea of actinide separation based on the extracted species of coordinated assembly nanoclusters is an important application of the concept of supramolecular assembly in the fields of radiochemistry and radionuclide separation.

报告摘要：Covalent organic frameworks (COFs) represent an emerging class of crystalline polymers with structural periodicity and inherent porosity and have attracted considerable attention over the past decade for promising applications in gas storage and separation, catalysis, sensor, optoelectronic devices and energy storage. Based on the covalent connectivity in different dimensions, COFs can be categorized into either two-dimensional (2D) layered structures or three-dimensional (3D) extended networks. Until now, most of work has focused on 2D COFs. In contrast, 3D COFs have been much less investigated, although they can possess numerous open sites and hierarchical pore structures that would make them attractive for gas adsorption and catalysis. This underdeveloped status can be attributed to their challenging synthesis, limited structural diversity and complicated structural determination. In this talk, we will present our recent progress in 3D COFs.

报告摘要：The knowledge on the formation, structure, and reactivity of low-coordinate transition-metal species forms the basis for the development of new 3d metal-catalyzed organic transformations and also disclosing the mysterious mechanisms of catalytic reactions. Aiming to deepen our knowledge on this type of reactive metal species, we have been working on the chemistry of low-coordinate zero-valent cobalt, iron and manganese complexes with N-heterocyclic carbene (NHC) and olefin ligation. This ligand set is found effective in stabilizing three-coordinate cobalt(0, -I), iron(0, -I), and manganese(0) complexes in the forms of [(NHC)M(olefin)2]0,1-. In this presentation, the synthesis, electronic structure, and reactivity of the three-coordinate zero-valent metal complexes, as well as their synthetic applications, will be discussed.
