TLDR
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

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.

Optically Detected Electron Spin Locking and Rotary Echo Trains in Molecular Excited States
TL;DR: In this paper, the rotary echoes and rotary echo trains have been detected for molecules in their excited triplet states by monitoring the microwave-induced modulation of the phosphorescence, and the results suggest that nuclear and electron spins in ground and excited states, acoustic phenomena in molecular solids, energy transfer, spin exchange, nuclear polarization, and a wide variety of additional processes can be optically detected.
