    Mechanically interlocked molecules in metal–organic frameworks
    (Royal Society of Chemistry, 2022-05-25) Saura-Sanmartin, Adrian; Pastor Vivero, Aurelia; Martinez-Cuezva, Alberto; Cutillas-Font, Guillermo; Alajarín, Mateo; Berná Cánovas, José; Química Orgánica
    Mechanically interlocked molecules (MIMs) have great potential in the development of molecular machinery due to their intercomponent dynamics. The incorporation of these molecules in a condensed phase makes it possible to take advantage of the control of the motion of the components at the macroscopic level. Metal–organic frameworks (MOFs) are postulated as ideal supports for intertwined molecules. This review covers the chemistry of the mechanical bond incorporated into metal–organic frameworks from the seminal studies to the latest published advances. We first describe some fundamental concepts of MIMs and MOFs. Next, we summarize the advances in the incorporation of rotaxanes and catenanes inside MOF matrices. Finally, we conclude by showing the study of the rotaxane dynamics in MOFs and the operation of some stimuli-responsive MIMs within MOFs. In addition to emphasising some selected examples, we offer a critical opinion on the state of the art of this research field, remarking the key points on which the future of these systems should be focused.

    Photoresponsive metal-organic frameworks as adjustable scaffolds in reticular chemistry
    (Multidisciplinary Digital Publishing Institute, 2022-06-27) Saura Sanmartín, Adrián; Saura Sanmartín, Adrián; Química Orgánica
    The easy and remote switching of light makes this stimulus an ideal candidate for a large number of applications, among which the preparation of photoresponsive materials stands out. The interest of several scientists in this area in order to achieve improved functionalities has increase parallel to the growth of the structural complexity of these materials. Thus, metal-organic frameworks (MOFs) turned out to be ideal scaffolds for light-responsive ligands. This review is focused on the integration of photoresponsive organic ligands inside MOF crystalline arrays to prepare enhanced functional materials. Besides the summary of the preparation, properties and applications of these materials, an overview of the future outlook of this research area is provided.
