Spin-Crossover in an Exfoliated 2D Coordination Polymer and Its Implementation in Thermochromic Films

Development of novel 2D materials with singular and thrilling properties has aroused large interest due to the novel unexpected applications that can be derived from there. In this sense, coordination polymers (CPs) have appeared as matching candidates thanks to their rational chemical design and th...

In this sense, coordination polymers (CPs) have appeared as matching candidates thanks to their rational chemical design and the added-value properties given by the presence of metal ions.

The application of this top-down technique results in the formation of flakes with controlled thicknesses, down to 1-2 nm thick (mostly mono- and bilayer), that retain the chemical composition and SCO interconversion of the bulk material. Moreover, these flakes can be handled as stable colloidal dispersions for many days. This allows for a controlled transfer to solid substrates and the formation of thermochromic polymeric films as a proof-of-concept of device. These first results will definitely open new venues and opportunities for the investigation and future integration of these original switchable 2D materials in devices. 22018-01-0120182018-01-01Articlehttp://purl.org/coar/resource_type/c_6501AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/195757https://dx.doi.org/urn:doi:10.1021/acsanm.8b00341reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengMinisterio de Economía y Competitividad https://doi.org/10.13039/501100003329 MAT2015-70615-RMinisterio de Economía y Competitividad https://doi.org/10.13039/501100003329 CTQ2015-65439-RMinisterio de Economía y Competitividad https://doi.org/10.13039/501100003329 FIS2015-64886-C5-3-PMinisterio de Economía y Competitividad https://doi.org/10.13039/501100003329 BES-2015-071492Ministerio de Economía y Competitividad https://doi.org/10.13039/501100003329 SEV-2013-0295Agència de Gestió d'Ajuts Universitaris i de Recerca https://doi.org/10.13039/501100003030 2014/SGR-301European Commission https://doi.org/10.13039/501100000780 676598open accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
