Special Issue "Spin-Crossover Beyond the Immediate Tribute"
Deadline for manuscript submissions: closed (30 May 2019).
Interests: My main research efforts are focused on the investigation of the relationships between the structural and physical properties in solids with a preference, but not exclusively, for molecular materials. These studies fall within the field of expertise of crystallography and address the different scales of matter, distinct environments (temperature, pressure, light) and various types of samples (crystals, nanoparticles, powders, films, raw material) in connection with magnetism, conductivity and optical features. Examples of the investigated fields are molecular superconductors, molecular magnets, spin-crossover phenomena and organic–inorganic hybrid materials
Keywords: Crystallography, X-rays, Solid-state, Phase transition, High-pressure, Low-temperature, Molecular crystals, Spin-crossover, Multi-functional materials
Interests: Switchable molecules, especially spin crossover molecules, constitute my main research topic, ranging from molecular solid-state chemistry to the molecular materials sciences. The story of a compound starts with the design of molecule (the ligand and the coordination complex) and its integration in a molecular crystal. The interplay between the molecular and the material scales leads to a wide range of properties (ferro– and antiferro–elastic interactions, elastic frustration, bidirectional photoswitching, phase transitions, polymorphism, etc.). Photoswitching is particularly attractive since unusual states can be reached, at various scales (from molecules to materials, from crystals to nanoparticles, from femtoseconds to hours).
Borders are the melting pot of cultural effervescence; they are also places of perdition where danger lurks. This observation applies to science; it is indeed often at the borders of well-recognized scientific fields that ideas and major improvements take place, even though care must be taken not to get lost in the background. Spin-crossover (SCO) is a topic that is truly located at the crossroads of a wide variety of approaches and characterization techniques, a large panel of research fields and communities, as well as diverse targets ranging from fundamental questioning to practical developments. Consequently, working on the SCO phenomenon can potentially lead to advancements in knowledge and know-how that turn out to be relevant in other, sometimes unanticipated scientific fields. The open access journal Magnetochemistry has earlier devoted a Special Issue to SCO (January 2016). The success of the latter and the high quality of the published results first illustrated the above arguments and, second, urged the dedication of another Special Issue to SCO, notably because of the amazing and growing amount of progress made on this exciting topic. This Special Issue is therefore devoted to Spin-CrossOver, focusing on the promotion of its multi-disciplinary aspects, and providing authors with a place to present their latest discoveries and the opportunity to offer a tribute beyond their usual audience.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
