The main experimental results and their connections with devices such as light-emitting diodes and electronic memory devices are summarized, and the scientific and technological issues that make organic spintronics a young but exciting field are outlined.Abstract:
Organic semiconductors are characterized by a very low spin–orbit interaction, which, together with their chemical flexibility and relatively low production costs, makes them an ideal materials system for spintronics applications. The first experiments on spin injection and transport occurred only a few years ago, and since then considerable progress has been made in improving performance as well as in understanding the mechanisms affecting spin-related phenomena. Nevertheless, several challenges remain in both device performance and fundamental understanding before organic semiconductors can compete with inorganic semiconductors or metals in the development of realistic spintronics applications. In this article we summarize the main experimental results and their connections with devices such as light-emitting diodes and electronic memory devices, and we outline the scientific and technological issues that make organic spintronics a young but exciting field.read more

Supramolecular spin valves

TL;DR: An original spin-valve device is presented in which a non-magnetic molecular quantum dot is laterally coupled through supramolecular interactions to TbPc(2) single-molecule magnets (Pc=phthalocyanine), resulting in magnetoresistance ratios up to 300% at temperatures less than 1 K.

Molecular magnetism: from chemical design to spin control in molecules, materials and devices
TL;DR: The field of molecular magnetism is rapidly evolving towards the use of magnetic molecules and molecule-based magnetic materials in physics-driven and nanotechnology-driven fields, in particular molecular spintronics, quantum technologies, metal-organic frameworks (MOFs) and 2D materials as discussed by the authors.

TL;DR: It is demonstrated that the HFI does indeed have a crucial role in all three spin responses and OLED films based on the D-polymers show substantially narrower magneto-electroluminescence and ODMR responses, and OSV devices based on D- polymers show a substantially larger magnetoresistance.

Zethrenes, extended p-quinodimethanes, and periacenes with a singlet biradical ground state.
TL;DR: This Account discusses the chemistry and physics of three types of PHs with a significant singlet biradical character, primarily developed in this group, and finds that Clar's aromatic sextet rule, which is useful for the closed-shell PAHs, can also predict the relative biradicals character of benzenoid PH-based singletBiradicaloids.

Theory of spin injection into conjugated organic semiconductors
P. Paul Ruden,Darryl L. Smith +1 more
TL;DR: In this article, the authors present a theoretical model to describe electrical spin injection from a ferromagnetic contact into a conjugated organic semiconductor, which requires a spin-dependent barrier to electrical injection that may be due either to tunneling through the depletion region of a large Schottky barrier, or to a thin, insulating, interface layer.

Absence of spin transport in the organic semiconductor Al q 3
TL;DR: In this paper, the magnetoresistance properties of spin-valve structures were investigated and it was shown that spin injection and transport is limited by holes only and is injection-limited.

Organic electronics: spintronics goes plastic.
TL;DR: A series of pioneering experiments demonstrates that the integration of molecular and spin electronics is also possible and challenges the conventional view that spin-related phenomena are only related to inorganic materials.
