17 p, 1.2 MB Postsynthetic Selective Ligand Cleavage by Solid-Gas Phase Ozonolysis Fuses Micropores into Mesopores in Metal-Organic Frameworks / Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Xu, Heng (Institut Català de Nanociència i Nanotecnologia) ; Albalad, Jorge (Institut Català de Nanociència i Nanotecnologia) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Herein we report a novel, ozone-based method for postsynthetic generation of mesoporosity in metal-organic frameworks (MOFs). By carefully selecting mixed-ligand Zr-fcu-MOFs based on organic ligand pairs in which one ligand has ozone-cleavable olefin bonds and the other ligand is ozone-resistant, we were able to selectively break the cleavable ligand via ozonolysis to trigger fusion of micropores into mesopores within the MOF framework.

7 p, 804.7 KB Confining Functional Nanoparticles into Colloidal Imine-Based COF Spheres by a Sequential Encapsulation–Crystallization Method / Rodríguez San-Miguel, David (Universidad Autónoma de Madrid. Departamento de Química Inorgánica) ; Yazdi, Amirali (Institut Català de Nanociència i Nanotecnologia) ; Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Pérez Carvajal, Javier (Institut Català de Nanociència i Nanotecnologia) ; Puntes, Víctor (Institut Català de Nanociència i Nanotecnologia) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia) ; Zamora, Félix (Universidad Autónoma de Madrid. Departamento de Química Inorgánica)
Here, a two-step method is reported that enables imparting new functionalities to covalent organic frameworks (COFs) by nanoparticle confinement. The direct reaction between 1,3,5-tris(4-aminophenyl)benzene and 1,3,5-benzenetricarbaldehyde in the presence of a variety of metallic/metal-oxide nanoparticles resulted in embedding of the nanoparticles in amorphous and non-porous imine-linked polymer organic spheres (NP@a-1).

4 p, 1.8 MB A Coordinative Solubilizer Method to Fabricate Soft Porous Materials from Insoluble Metal–Organic Polyhedra / Carné Sánchez, Arnau (Institut Català de Nanociència i Nanotecnologia) ; Craig, Gavin A. (Kyoto University. Institute for Integrated Cell-Material Science) ; Larpent, Patrick (Kyoto University. Institute for Integrated Cell-Material Science) ; Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Urayama, Kenji (Kyoto Institute of Technology) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia) ; Furukawa, Shuhei (Kyoto University. Department of Synthetic Chemistry and Biological Chemistry)
Porous molecular cages have a characteristic processability arising from their solubility, which allows their incorporation into porous materials. Attaining solubility often requires covalently bound functional groups that are unnecessary for porosity and which ultimately occupy free volume in the materials, decreasing their surface areas.

6 p, 767.9 KB Zigzag ligands for transversal design in reticular chemistry : unveiling new structural opportunities for metal-organic frameworks / Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Grancha, Thais (Institut Català de Nanociència i Nanotecnologia) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Juanhuix, Judith (ALBA Laboratori de Llum de Sincrotró) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Herein we describe the topological influence of zigzag ligands in the assembly of Zr(IV) metal-organic frameworks (MOFs). Through a transversal design strategy using reticular chemistry, we were able to synthesize a family of isoreticular Zr(IV)-based MOFs exhibiting the bcu - rather than the fcu - topology. [...]

7 p, 353.9 KB Squaramide‐IRMOF‐16 analogue for catalysis of solvent‐free, epoxide ring‐opening tandem and multicomponent reactions / Vignatti, Claudia (Institut Català de Nanociència i Nanotecnologia) ; Luis-Barrera, Javier (Universidad Autónoma de Madrid. Departamento de Química Orgánica) ; Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Mas-Ballesté, Rubén (Universidad Autónoma de Madrid. Departamento de Química Inorgánica) ; Alemán, José (Universidad Autónoma de Madrid. Departamento de Química Orgánica) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Tandem and multicomponent one-pot reactions are highly attractive because they enable synthesis of target molecules in a single reaction vessel. However, they are difficult to control, as they can lead to the formation of many undesired side-products. [...]

22 p, 989.8 KB Continuous one-step synthesis of porous M-XF6-based metal-organic and hydrogen-bonded frameworks / Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Garzón Tovar, Luis (Institut Català de Nanociència i Nanotecnologia) ; Yazdi, Amirali (Institut Català de Nanociència i Nanotecnologia) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Juanhuix, Jordi (ALBA Laboratori de Llum de Sincrotró) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Metal‐organic frameworks (MOFs) built up from connecting M‐XF₆ pillars through N‐donor ligands are among the most attractive adsorbents and separating agents for CO₂ and hydrocarbons today. [...]
