Here we propose a mechanism by which spin-polarization can be generated dynamically in chiral molecular systems undergoing photoinduced electron transfer. The proposed mechanism explains how spin-polarization emerges in systems where charge transport is dominated by incoherent hopping, mediated by spin-orbit and electronic exchange couplings through an intermediate charge transfer state. We derive a simple expression for the spin-polarization that predicts a nonmonotonic temperature dependence… Expand

TLDR
This work explores the effect of electron transfer on spins in chiral single radicals and chiral radical pairs using Nakajima-Zwanzig theory and demonstrates that the out of phase electron spin echo envelope modulation pulse electron paramagnetic resonance experiment would be able to detect this effect in oriented radical pairs.

Spintronics and chirality: spin selectivity in electron transport through chiral molecules.
TLDR
This article reviews recent developments in the understanding of the chiral-induced spin selectivity (CISS) effect, and the possible application of the CISS effect for memory devices is described. Expand
Spin Selectivity in Photoinduced Charge-Transfer Mediated by Chiral Molecules.
TLDR
Recent approaches used to detect and to analyze spin selectivity in photoinduced charge transfer including spin-transfer torque for local magnetization, nanoscale charge separation and polarization, and soft ferromagnetic substrate magnetization- and chirality-dependent photoluminescence are highlighted. Expand
Chiral Molecules and the Spin Selectivity Effect
TLDR
A simplified model is described in which the chiral molecule’s spin polarization is enhanced by a spin blockade effect to generate large spin filtering, implying that exchange interactions and Pauli exclusion constraints are an important aspect of CISS. Expand
Theory of Chiral Induced Spin Selectivity.
TLDR
It is proved that in a situation with one magnetic lead, the other lead will become magnetized and this results from the interplay between the spin-orbit coupling in the chiral molecule and the magnetized lead. Expand
Chiral-induced spin selectivity in the formation and recombination of radical pairs: cryptochrome magnetoreception and EPR detection
That the rates and yields of reactions of organic radicals can be spin dependent is well known in the context of the radical pair mechanism (RPM). Less well known, but still well established, is theExpand
Chirality Control of Electron Transfer in Quantum Dot Assemblies.
TLDR
Findings imply that the CD strength of the QD exciton transition(s) may be used as a predictor for the spin-dependent electron transfer, indicating that chiral imprinting of the dots may lie at the origin of this phenomenon. Expand

TLDR
Fluorescence microscopy is used to visualize the effects of spin-dependent charge transport in self-assembled monolayers of double-stranded DNA on ferromagnetic substrates to discuss the results in the context of the current literature on the chiral-induced spin selectivity effect across various systems.
