• Metal–Organic Polyhedra as Building Blocks for Porous Extended Networks

  Khobotov-Bakishev A., Hernández-López L., von Baeckmann C., Albalad J., Carné-Sánchez A., Maspoch D. Advanced Science; 9 (11, 2104753) 2022. 10.1002/advs.202104753. IF: 16.806

  Metal–organic polyhedra (MOPs) are a subclass of coordination cages that can adsorb and host species in solution and are permanently porous in solid-state. These characteristics, together with the recent development of their orthogonal surface chemistry and the assembly of more stable cages, have awakened the latent potential of MOPs to be used as building blocks for the synthesis of extended porous networks. This review article focuses on exploring the key developments that make the extension of MOPs possible, highlighting the most remarkable examples of MOP-based soft materials and crystalline extended frameworks. Finally, the article ventures to offer future perspectives on the exploitation of MOPs in fields that still remain ripe toward the use of such unorthodox molecular porous platforms. © 2022 The Authors.

• Multicomponent, Functionalized HKUST-1 Analogues Assembled via Reticulation of Prefabricated Metal-Organic Polyhedral Cavities

  Khobotov-Bakishev A., Von Baeckmann C., Ortín-Rubio B., Hernández-López L., Cortés-Martínez A., Martínez-Esaín J., Gándara F., Juanhuix J., Platero-Prats A.E., Faraudo J., Carné-Sánchez A., Maspoch D. Journal of the American Chemical Society; 2022. 10.1021/jacs.2c06131.

  Metal-organic frameworks (MOFs) assembled from multiple building blocks exhibit greater chemical complexity and superior functionality in practical applications. Herein, we report a new approach based on using prefabricated cavities to design isoreticular multicomponent MOFs from a known parent MOF. We demonstrate this concept with the formation of multicomponent HKUST-1 analogues, using a prefabricated cavity that comprises a cuboctahedral Rh(II) metal-organic polyhedron functionalized with 24 carboxylic acid groups. The cavities are reticulated in three dimensions via Cu(II)-paddlewheel clusters and (functionalized) 1,3,5-benzenetricarboxylate linkers to form three- and four-component HKUST-1 analogues. © 2022 The Authors.

• Synthesis of Polycarboxylate Rhodium(II) Metal–Organic Polyhedra (MOPs) and their use as Building Blocks for Highly Connected Metal–Organic Frameworks (MOFs)

  Grancha T., Carné-Sánchez A., Zarekarizi F., Hernández-López L., Albalad J., Khobotov A., Guillerm V., Morsali A., Juanhuix J., Gándara F., Imaz I., Maspoch D. Angewandte Chemie - International Edition; 60 (11): 5729 - 5733. 2021. 10.1002/anie.202013839. IF: 15.336

  Use of preformed metal-organic polyhedra (MOPs) as supermolecular building blocks (SBBs) for the synthesis of metal-organic frameworks (MOFs) remains underexplored due to lack of robust functionalized MOPs. Herein we report the use of polycarboxylate cuboctahedral RhII-MOPs for constructing highly-connected MOFs. Cuboctahedral MOPs were functionalized with carboxylic acid groups on their 12 vertices or 24 edges through coordinative or covalent post-synthetic routes, respectively. We then used each isolated polycarboxylate RhII-MOP as 12-c cuboctahedral or 24-c rhombicuboctahedral SBBs that, upon linkage with metallic secondary building units (SBUs), afford bimetallic highly-connected MOFs. The assembly of a pre-synthesized 12-c SBB with a 4-c paddle-wheel SBU, and a 24-c SBB with a 3-c triangular CuII SBU gave rise to bimetallic MOFs having ftw (4,12)-c or rht (3,24)-c topologies, respectively. © 2020 Wiley-VCH GmbH
