Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Amazing ammonia</bold>: The molecular spin state of Ni^II porphyrin, supported on a ferromagnetic Co surface, can be reversibly switched between spin‐off (S=0) and spin‐on (S=1) states upon coordination and decoordination of the gaseous ligand NH₃, respectively (see picture). This finding clearly indicates the possible use of the system as a single‐molecule‐based magnetochemical sensor and in spintronics.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1xps7skt" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
