Single-chain magnets assembled in cobalt(II) metal-organic frameworks
Single-chain magnets (SCMs) are one-dimensional (1D) coordination polymers that exhibit magnetic bistability and have potential applications in high-density information processing. Usually SCMs are magnetically isolated chains stacked by hydrogen bonds or π···π stacking; however, with the rapid development of metal-organic frameworks (MOFs), coordination chains assembled in MOFs have also shown SCM behaviour when 1D magnetic correlation is strong enough than the other two dimensions. The high-dimensional framework of MOFs could also help for the formation of the coordination chains that cannot formed in isolated one-dimensional coordination system. This feature article highlights the progress in this field by summarizing cobalt(II)-based MOFs exhibiting SCM behaviour and classifying them into categories according to the bridging ligands within the CoII chains, to provide fundamentals for the further studies on the magnetic properties of coordination chains assembled in MOFs.
