  • Synthesis of a chiral rod-like metal–organic framework from a preformed amino acid-based hexanuclear wheel

    Grancha T., Ferrando-Soria J., Armentano D., Pardo E. Journal of Coordination Chemistry; 72 (8): 1204 - 1221. 2019. 10.1080/00958972.2019.1575371. IF: 1.685

    We report the two-step synthesis of a chiral rod-like metal-organic framework (MOF). The chemical approach consists on the use of a previously prepared oxamato-based homochiral hexanuclear wheel, the ligand being a derivative of the natural amino acid l-alanine, with formula (Me4N)6{CuII6[(S)-alama])6}·10H2O (1) [where (S)-alama=(S)-N-(ethyl oxoacetate)alanine]. The anionic hexacopper(II) wheels, stabilized by the presence of templating tetramethylammonium counter-cations, disassemble in the presence of cationic square-planar [Ni(cyclam)]2+ complexes to yield, after a supramolecular reorganization process that involves axial coordination of the [Ni(cyclam)]2+ cations through the free carbonyl groups of the copper(II) moieties, a neutral chiral rod-like, three-dimensional (3D) MOF with formula [Ni(cyclam)][Cu(S)-alama]2·16H2O (2). The resulting MOF constitutes one of the few examples where such a high-nuclearity metal complex is used as precursor for the construction of rod-like MOFs. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.

  • Zigzag Ligands for Transversal Design in Reticular Chemistry: Unveiling New Structural Opportunities for Metal-Organic Frameworks

    Guillerm V., Grancha T., Imaz I., Juanhuix J., Maspoch D. Journal of the American Chemical Society; 140 (32): 10153 - 10157. 2018. 10.1021/jacs.8b07050. IF: 14.357

    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. Our findings underscore the value of the transversal parameter in organic ligands for dictating MOF architectures. © 2018 American Chemical Society.
