Voltage-Induced Switching Dynamics of a Coupled Spin Pair in a Molecular Junction

“…2 (e), which shows the corresponding DOS for molecule 2. In particular this means that G (1) σσ and G (2) σσ have a negligible (finite) overlap, or in other words, the spin-projections of the electronic density are localized (delocalized), in the anti-ferromagnetic (ferromagnetic) regime, which has a large influence on the transport properties as we shall see next.…”

“…Arrays of magnetic molecules inserted between conducting leads, moreover, provide an important forum to investigate fundamental magnetic properties of finite one-dimensional Ising or Heisenberg chains [14][15][16] as well as potential for electrical and thermal control of the magnetic state. Certain classes of molecules, e.g., metal-phthalocyanines (MPc) and metal-porhyrins (MP) present chemical stability with specific optical and electrical properties make them highly appreciated for technological applications including organic field effect transistors [17,18], light emitting devices [19,20] and photovoltaic cells [21], and for fundamental studies [7,[22][23][24][25][26][27].While incorporation of magnetic elements in molecular compounds can have a significant effect on the overall molecular transport properties [7], the main established route to spintronics manipulations entails external magnetic fields [2] or ferromagnetic electrodes [28,29], often exploiting spin transfer torques from spin-polarized scattering [30] or Coulomb interaction [31]. Here, we propose a different route to molecular spintronics based on voltage induced control of magnetic interactions that allows for all electrical control of the transport properties.…”

Luminescence and Single‐Molecule‐Magnet Behaviour in Lanthanide Coordination Complexes Involving Benzothiazole‐Based Tetrathiafulvalene Ligands

“…[5][6][7] The origin of this keen interest comes from their particular magnetic characteristics (high magnetic moments and strong magnetic anisotropy) and specific luminescence. Both SMMs and luminescent materials have a plethora of potential applications, for example, high-density data storage, spintronics and quantum computing, [8][9][10][11][12][13][14][15] organic light-emitting diodes (OLEDs), [16] time-resolved fluoro-immunoassays, [17] biosensors [18,19] and time-resolved imaging. [20] In the molecular-magnetism field, the luminescence was recently exploited to provide a high level of comprehension of the magnetic properties.…”

Synthetic approaches to asymmetric phthalocyanines and their analogues

“…280 Finally, two asymmetrically substituted phthalocyanines (102 and 103) of A 3 B type were prepared by statistical condensation and used to form double-decker terbium complexes. [281][282][283] The synthetic routes are tedious, but they provide an access to the derivatives represented in Figure 7. …”
