Spin transition complexes are an interesting class of materials
exhibiting molecular bistability with potential applications in
nanotechnological devices as memory storage units, sensors or
displays. Since the discovery of the spin transition phenomenon
in tris(N,N-dialkyldithiocarbamato) iron(III) complexes, numerous
investigations have been devoted to this field of molecular
magnetism. The spin transition phenomenon is probably the most
spectacular example of bistability in molecular chemistry. However,
it is a challenge to obtain spin transition materials when working
under ambient conditions (eg. room temperature and pressure),
which would be highly advantageous for potential applications. So
far, only some Fe(II) and Fe(III) molecular systems have shown
temperature-induced spin transitions around and even above room
temperature. Within this review, we discuss the characteristics of
this class of bistable compounds in detail and we try to draw more
general conclusions regarding the integration, implementation and
application of spin transition compounds as switching elements in
hybrid molecular devices.
