Two Consecutive Magneto-Structural Gas-Solid Transformations in Non-Porous Molecular Materials
2018
Modification of the magnetic properties in a solid-state material upon external stimulus has attracted much attention in the recent years for their potential applications as switches and sensors. Within the field of coordination polymers, gas sorption studies typically focus on porous solids, with the gas molecules accommodating in the channels. Here we present a 1D non-porous coordination polymer capable of incorporating HCl gas molecules, which not only causes a reordering of its atoms in the solid state but also provokes dramatic changes in the magnetic behavior. Subsequently, a further solid-gas transformation can occur with the extrusion of HCl gas molecules causing a second structural…
Exploiting Reaction-Diffusion Conditions to Trigger Pathway Complexity in the Growth of a MOF.
2021
Coordination polymers (CPs), including metal–organic frameworks (MOFs), are crystalline materials with promising applications in electronics, magnetism, catalysis, and gas storage/separation. However, the mechanisms and pathways underlying their formation remain largely undisclosed. Herein, we demonstrate that diffusion-controlled mixing of reagents at the very early stages of the crystallization process (i.e., within ≈40 ms), achieved by using continuous-flow microfluidic devices, can be used to enable novel crystallization pathways of a prototypical spin-crossover MOF towards its thermodynamic product. In particular, two distinct and unprecedented nucleation-growth pathways were experimen…
Isostructural compartmentalized spin-crossover coordination polymers for gas confinement
2016
[EN] Here we present two FeII coordination polymers that possess discrete compartments suitable for CO2 physisorption despite the lack of permanent channels. The two crystalline materials, of general formula [Fe(btzbp)3](X)2 (X = ClO4 or BF4), present voids of ca. 250 Å3, which each can accommodate up to two CO2 molecules. The abrupt spin transition can be modified upon CO2 sorption, and different magnetic behaviour is observed depending on the number of molecules sorbed.

Gas confinement in compartmentalized coordination polymers for highly selective sorption
2016
Discrimination between different gases is an essential aspect for industrial and environmental applications involving sensing and separation. Several classes of porous materials have been used in this context, including zeolites and more recently MOFs. However, to reach high selectivities for the separation of gas mixtures is a challenging task that often requires the understanding of the specific interactions established between the porous framework and the gases. Here we propose an approach to obtain an enhanced selectivity based on the use of compartmentalized coordination polymers, named CCP-1 and CCP-2, which are crystalline materials comprising isolated discrete cavities. These compar…
A Mixed-Ligand Approach for Spin-Crossover Modulation in a Linear FeII Coordination Polymer
2014
In this work, we present a family of Fe(II) coordination polymers of general formula [Fe(btzx)(3-3x)(btix)(3x)](ClO4)2 with interesting spin-crossover properties. These coordination polymers have been synthesized using chemical mixtures of two different but closely related ligands, 1,4-bis(tetrazol-1-ylmethyl)benzene (btzx) and 1,4-bis(triazol-1-ylmethyl)benzene (btix), and the effect of a gradual substitution of the ligand in the spin transition temperature has been investigated. Several chemical mixtures have been structurally characterized by X-ray powder diffraction indicating a clear critical amount in the composition of the mixture after which mixed phases rather than a single phase c…
Interplay between spin transition and gas sorption in compartmentalized coordination polymers
2019
El trabajo descrito en esta tesis se enmarca dentro de los polímeros de coordinación compartimentalizados. Los polímeros de coordinación son materiales híbridos orgánicos-inorgánicos formados por un metal rodeado por unos ligandos orgánicos unidos mediante enlace de coordinación y se pueden obtener estructuras que se extienden en una, dos o tres direcciones del espacio. Las infinitas posibilidades que existen debido a la gran variedad de metales disponibles y especialmente, a la posibilidad de sintetizar múltiples ligandos orgánicos permite diseñar químicamente materiales con propiedades “a la carta”, además de la posibilidad de presentar multifuncionalidad, esto es, la combinación de diver…

How do you unveil pathway complexity in a crystallization process? In their Research Article on page 15920, Alessandro Sorrenti, Marco D′Abramo, Guillermo Mínguez Espallargas, Josep Puigmartí-Luis, and co-workers show that harnessing a reaction-diffusion (RD) process within a continuous flow microfluidic device, and on a millisecond timescale, is key to enable two unprecedented nucleation-growth pathways during a MOF synthesis.
