Abstract
This thesis is a preliminary investigation into the synthesis of Fe(II) triazole spin crossover compounds (SCO) using novel techniques that are easily scalable for the production of large quantities. These techniques are the direct-contact synthesis of solid reagents mixed under ambient conditions and thin-film synthesis via in situ airbrushing. Three compounds [Fe(atrz)3]SO4 (1), [Fe(Htrz)2(trz)](BF4) (2), and [Fe(atrz)3](BF4)2 (3) were synthesized using these novel techniques and analyzed and characterized with regard to their respective traditional solution-state synthesis. Analysis shows that for 1, the direct-contact and thin-film methods successfully synthesize the same compound as the traditional synthetic method yielding very similar SCO properties. Compound 2 is known to exist in a variety of forms, and it is likely that the direct-contact method yields a multi-phase sample of hydrated forms that potentially dehydrate upon heating. The thin-film method likely synthesizes the same compound as the solution-state with very similar SCO properties. The direct-contact method of compound 3 synthesises the polymorph. More analysis is required to determine with accuracy the form of the thin-film method and its corresponding SCO properties. The overall results demonstrate that novel direct- contact and thin-film methods are viable techniques for synthesizing SCO materials on a large- scale.
