Polímeros de coordinación conmutables de hierro(II) para aplicaciones multifuncionalesSwitchable iron(II) coordination polymers for multifunctional applications

Abstract

In recent years, interest in coordination polymers (CPs) has grown rapidly with the demand for new materials that exhibit improved properties, are more cost-effective or can combine several desired properties. This particular development has been driven by crystal engineering, which entails the self-assembly of organic ligands and metal ions with specific functionality and directionality. This enables the design and synthesis of new molecules with targeted properties. Accordingly, a wide variety of CPs with potential applications in catalysis,1 gas sorption,2 luminescence,3 drug delivery,4 sensing,5 magnetism6 and anion exchange7 have been reported. Among them, the family of spin crossover materials (SCO) and coordination polymers exhibiting electrical properties hasgarnered considerable attention.The SCO effect occurs when the metal ion in coordination compounds undergoes a reversible and reproducible spin transition between the low spin (LS) and high spin (HS) electronic states, under the influence of external stimuli, such as temperature, pressure, light, magnetic field and the absorption/desorption of guest molecules...
