Variability of the Conductance Changes Associated with the Change in the Spin State in Molecular Spin Crossover Complexes

Here, we examine the conductance changes associated with the change in spin state in a variety of different structures, using the example of the spin crossover complex [Fe(H2B(pz)2)2(bipy)] (pz = (pyrazol-1-yl)-borate and bipy = 2,2 '-bipyridine) and [Fe(Htrz)2(trz)](BF4)] (Htrz = 1H-1,2,4-triazole) thin films. This conductance change is highly variable depending on the mechanism driving the change in spin state, the substrate, and the device geometry. Simply stated, the choice of spin crossover complex used to build a device is not the only factor in determining the change in conductance with the change in spin state.

Automated summary

In this study, we investigated the conductance changes associated with the change in spin state in different structures, with a focus on thin films. We found that the conductance change is influenced by factors such as the mechanism driving the spin state change, the substrate, and the device geometry.
