“…57,[66][67][68][69] Additionally, the coordination sphere of the metal ion can be easily modified allowing the inclusion of extra coordination points that makes possible the anchorage of the MMWs to surfaces and/or electrodes, expanding future perspectives in the design of spintronic devices. 70,71 On the other hand, the large acenes are not chemically very stable because of their open-shell character. However, this is not the case for those arising from an extension of them, acenes or cyclic-acenes, i.e.…”

Theoretical calculations on a series of molecular models based on amino derivatives of linear and cycled acenes acting as organic linkers between two copper(ii) ions have shown a wire-like magnetic behaviour, so that the intermetallic magnetic communication does not vanish when the linker becomes larger due to its polyradical nature. Hence, these models can be considered as molecular magnetic wires, which can be used as active components for molecular spintronics, where the information transport is based on spin carriers instead of the more conventional charge transport. The nature of the spin ground state along these two series of models is governed by the topology of the organic linker, in agreement with the spin polarization mechanism, allowing a wide diversity in the design of molecular spintronic circuits. Different approaches to search for the more stable spin configuration have been tested, the most efficient being the one that allows generating a guess function that agrees with the spin polarization mechanism.

“…However physical realization of a true spin filter accompanied with strong spin selective rectification action and low spin cross‐over field is hard area to pin down. Moreover, most of the hitherto reported spintronic system are transitional metals based and such systems have the disadvantages of low spin relaxation time and strong spin‐orbit interaction . Hence, a metal free magnetic material simultaneously showing high degree of filtration, rectification and switching is an area of further exploitation and need of modern spintronic industry.…”

Herein, we report on the potential multifunctional spintronic action of half-metallic graphitic carbon nitride (g-C 4 N 3 ). We observed electrostatic spin-crossover action at an applied electric field of À 0.77 V nm À 1 , which eventually leads to spinswitching action and change in sign of bias dependent spin injection coefficient. The system also acts as a spin polarized charge current rectifier with rectification ratio of 65.41 in spinup channel only. This electric field-controlled spin switching action and simultaneous existence of rectification action makes graphitic carbon nitride a perfect multifunctional spintronic system-an ideal material for quantum logic gate design. Results obtained have been substantiated through transmission spectra and transmission pathways analyses. An analysis of projected device density of states of the system and molecular projected self consistent Hamiltonian states analysis reveals that the electron flow of the system is mainly facilitated by 2p orbitals of C and N atoms.[a] R. . The MPSH states (isovalue: 0.0011 Å), corresponding to the SOHMO of the obtained g-C 4 N 3 system at À 1 V for spin-up (a) and spin-down (b) channel and at + 1 V for spin-up (c) and spin-down (d) channel. 4 5 6 7 8

Spintronics, a new discipline focusing on the spindependent transport process of electrons, has been developing rapidly. Spin valves are the most significant carriers of spintronics utilizing the spin freedom of electrons. It is expected to pierce "Moore's Law" and become the core component in processors of the next generation. Organic semiconductors advance in their adjustable band gap, weak spin-orbit coupling and hyperfine interaction, excellent filmforming property, having enormous promise for spin valves.Here, the principle of spin valves is introduced, and the history and progress in organic spin injection and transport materials are summarized. Then we analyze the influence of spinterface on device performance and introduce reliable methods of constructing organic spin valves. Finally, the challenges for spin valves are discussed, and the future is proposed. We aim to draw the attention of researchers to organic spin valves and promote further research in spintronics through this paper.
