Amazing ammonia : 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 NH 3 , respectively (see picture). This finding clearly indicates the possible use of the system as a single‐molecule‐based magnetochemical sensor and in spintronics.
