Magnetic nanoporous coordination polymers

The use of organic molecules as an alternative strategy for achieving new nanoporous metal–organic materials has become an attractive prospect. So far, the use of chemical coordination or crystal engineering techniques allows the systematic design of open-framework structures with a considerable range of modulatable pore sizes and functionalities using different organic ligands such as phosphane, cyano groups, N,N′-type ligands and polycarboxylic acids. Furthermore, the use of transition metal ions opens the possibility to obtain nanoporous materials with additional electrical, optical or magnetic properties. Among them, the search for magnetic open-framework structures has become a major challenge due to their potential applications in the development of low-density magnetic materials, magnetic sensors and intelligent or multifunctional materials.
