We synthesised a series of Iron(II)-triazole compounds and used the electrospinning procedure to incorporate spin crossover compounds (SCO) into polylactic acid polymer fibers. Composite fiber/SCO compounds of [Fe(NH2-trz)(3)](BF4)(2) as well as [Fe(Htrz)(2)(trz)]BF4 were investigated via Mossbauer spectroscopy at 293 K and 77 K. The Mossbauer studies show that the spin crossover behavior is maintained in the polymer matrix.
