Description:Research Seminar Abstract\n\nThe electronic absorption and magn
 etic properties of iron(II) are vastly different depending on the spin sta
 te. Iron(II) can reversibly switch its spin state through perturbation\, l
 ike temperature\, intermolecular interactions\, coordination environment\,
  or moderate changes on the ligand (e.g. isomerization\, protonation). How
 ever\, to our knowledge\, there are no reports of spin state switching bei
 ng promoted by post synthetic modifications on iron(II) compounds using mi
 ld and efficient reactions. Through post synthetic reactions\, reactive gr
 oups can be included on the iron(II) bound ligand with more synthetic ease
  than traditional methods and can provide access to novel spin switching c
 ompounds and unique molecular sensors. A ligand was designed to provide op
 en coordination sites and reactive groups to allow post synthetic reaction
 s. The structure\, magnetic characterization\, and analyses of various pos
 t synthetic modifications of the novel iron(II) compound will be presented
