Supramolecular Interaction Tuning of Spin-Crossover in Pyrene/ Fullerene (C60) Tethered FeII-2,6-Di(pyrazol-1-yl)pyridine Complexes: Towards Switchable Molecular Devices
Original language description
A set of functional SCO systems based on FeII-2,6- di(pyrazol-1-yl)pyridine (BPP), FeII-BPP, featuring supramolecular pyrene and fullerene (C60) anchoring groups for nanocarbon materials are designed and synthesized. The pyrene tethered complexes [Fe(L1)2](BF4)2 and [Fe(L2)2](BF4)2 comprise structurally different BPP-pyrene ligand systems L1 (BPP-COOR, R = –CH2-pyrene) and L2 [BPP-CH2OR, R = –OC(CH2)-pyrene]. The [Fe(L1)2](BF4)2 complex showed gradual and high temperature SCO (T1/2 = ca. 450 K), whereas the [Fe(L2)2](BF4)2 complex remained trapped in the high spin (HS) state in the 300–5 K temperature range. On the other hand, the bulky fullerene (C60) tethered complex, [Fe(L3)2](BF4)2, is HS at 385 K and showed gradual but incomplete SCO, upon cooling, centered at 208 K. The results compiled in this study indicate the dominant role of intermolecular interactions in tuning/blocking SCO in the studied FeII-BPP complexes, a fact that needs to be carefully weighed while designing functional-SCO systems.
