“…Furthermore, novel spin injection methods via a spin pumping process (Ando et al, 2013; Jiang et al, 2015; Sun D. et al, 2016) or via hot spin electron emitting (Appelbaum et al, 2007; Gobbi et al, 2012) are also being actively explored. Indeed, a few recent reviews have made a relatively detailed introduction to spin injection and spinterface (Cinchetti et al, 2017; Jang and Richter, 2017; Sun and Mi, 2018), which can be referenced as well.…”

Because of the considerable advantages of functional molecules as well as supramolecules, such as the low cost, light weight, flexibility, and large area preparation via the solution method, molecular electronics has grown into an active and rapidly developing research field over the past few decades. Beyond those well-known advantages, a very long spin relaxation time of π-conjugated molecules, due to the weak spin-orbit coupling, facilitates a pioneering but fast-growing research field, known as molecular spintronics. Recently, a series of sustained progresses have been achieved with various π-conjugated molecular matrixes where spin transport is undoubtedly an important point for the spin physical process and multifunctional applications. Currently, most studies on spin transport are carried out with a molecule-based spin valve, which shows a typical geometry with a thin-film molecular layer sandwiched between two ferromagnetic electrodes. In such a device, the spin transport process has been demonstrated to have a close correlation with spin relaxation time and charge carrier mobility of π-conjugated molecules. In this review, the recent advances of spin transport in these two aspects have been systematically summarized. Particularly, spin transport in π-conjugated molecular materials, considered as promising for spintronics development, have also been highlighted, including molecular single crystal, cocrystal, solid solution as well as other highly ordered supramolecular structures.

“…An important challenge for the design of spintronic devices is the changeable control and switch of single molecules adsorbed on the surface of FM materials. Particularly, for the metalloporphyrins, an interesting example is the use of axial ligands of the porphyrin transition metal center to change the magnetism of the molecular component [98]. NO • was able to reversibly switch the spin state of the Co and Fe of porphyrins adsorbed on Ni(001) Co substrates, respectively.…”

The vital role played by porphyrins in cells and their use in therapeutic processes are well known. More recently, the technological applications of porphyrins have attracted the attention of researchers. Porphyrins have the property of half-metallic material, i.e., molecules that can host transition metals making feasible the production of spin-polarized electronic states at different channels. Therefore, porphyrins and hemeproteins are among the materials that have spin-filtering property to be applied in spintronics. Molecular spintronics is an emerging and highly relevant field due to their applications to the development of high-capacity informationstorage devices and quantum computers. The catalytic properties of porphyrins and related compounds such as the hemeproteins are also applicable in the fabrication of micro-/nanomotors (MNMs). In this chapter, we describe the advances and future perspectives in the technological applications of porphyrins and related compounds in spintronic devices and micro-/nanomotors.

“…The interactions of aromatic adsorbates with transition metal surfaces have been the subject of extensive theoretical and experimental investigations. [1][2][3][4][5][6][7][8][9] Co has 3d bands that are narrow, spin-split, close to the Fermi level, and partly lled, leading to strong chemisorption. This may be understood to result from Co d-orbitals that protrude at the positions of the Co surface atoms normal to the surface and interact with p-orbitals of pyrene.…”

“…Magnetoresistance arises at interfaces between ferromagnetic electrodes and organic compounds if chemisorbed proximal molecules and subsequent layers are precisely aligned. [1][2][3][4][5][6][7][8][9] The charge transport efficiencies of organic semiconductors are linked to the spatial overlap and orientation of adjacent porbitals. [10][11][12][13] Superconductivity arises in a duplex of two graphene sheets if one is twisted by a "magic angle" ($1.1 ) with respect to the other.…”
