Stimuli-responsive magnetic coordination polymers: from crystals to nanoparticles

2013

El trabajo descrito en esta tesis se enmarca en el ámbito de los polímeros de coordinación (PC). Estos sistemas representan un área importante dentro de la Química de los Materiales, siendo principalmente interesantes sus aplicaciones en catálisis, electrónica y óptica. Su origen data de principios de los años 60, donde se produjo la primera revisión de estructuras de compuestos inorgánicos que formaban cadenas.1 Los PC están formados por ligandos orgánicos y metales enlazados por enlaces de coordinación que se extienden infinitamente en 1, 2 o 3 dimensiones. En cuanto a su versatilidad química, las estructuras y propiedades varían en función de los metales o ligandos utilizados. Así pues, …

Size-Dependent Spin Switching in Robust Fe-triazole@SiO2 Spin-Crossover Nanoparticles with Ultrathin Shell

2019

<p>A familly of chemically robust hybrid [Fe(Htrz)2(trz)](BF4)@SiO2nanoparticles (NPs) presenting different sizes (from ca. 90 to 28 nm) and an ultrathin silica shell (< 3 nm) have been prepared. All NPs present a characteristic abrupt spin transition with a subsequent decrease in the width of the thermal hysteresis upon reducing the NP size.<br></p>

Smart molecular/MoS2 Heterostructures Featuring Light and Thermally-Induced Strain Driven by Spin Switching

2020

In this work we exploit the ability of spin-crossover molecules to switch between two spin states, upon the application of external stimuli, to prepare smart molecular/2D heterostructures. Through the chemical design of the hybrid interface, that involves a covalent grafting between the two components, we obtain a hybrid heterostructure formed by spin-crossover nanoparticles anchored on chemically functionalized monolayers of semiconducting MoS2. In the resulting hybrid, the strain generated by the molecular system over the MoS2 layer, as a consequence of a thermal or light-induced spin switching, results in a dramatic and reversible change of its electrical and optical properties. This nov…
