Floetotto, Henrik;Secker, Tim;Koegerler, Paul;Besson, Claire research published 《 Amine-Functionalized Spin Crossover Building Blocks》, the research content is summarized as follows. Bistable spin crossover complexes such as [Fe{HB(pz)3}2] (pzH = pyrazole) show promise for sensor applications and elec.-controlled data storage units, but exploiting their potential hinges on their integration into a functional environment. We here present a system enabling such covalent post-functionalization steps in both sym. and asym. patterns, based on the amine-functionalized complex [Fe{HB(4-NH2pz)(pz)2}2], obtained by reduction of the nitro analog. The building block aspects of [Fe{HB(4-NH2pz)(pz)2}2] are showcased by its transformation into amide, imine and azo derivatives, which are structurally and magnetically characterized. All tris(pyrazolyl)borate complexes retain the spin crossover properties of their parent compound, with spin crossover temperatures ranging from 350 to 430 K. The transition parameters are correlated with the electronic properties of the functionalizing group, opening the possibility of fine-tuning the spin crossover properties of the building block as it is integrated in the environment of choice.
