Implementation of spin crossover compounds into electrospun nanofibers
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 Mössbauer spectroscopy at 293 K and 77 K. The Mössbauer studies show that the spin crossover behavior is maintained in the polymer matrix.
