Title: Chirality Control of Electron Transfer in Quantum Dot Assemblies

Abstract

Electron spin and molecular chirality are emerging as factors that can be used effectively to direct charge flow at the molecular scale. We discuss order of magnitude effects of molecular chirality on electron-transfer rates between quantum dots (QDs) in chiral QD assemblies. Indeed, both the circular polarization of the light that excites the electron donor and the imprinted chirality of the acceptor QDs affect the dot-to-dot electron-transfer kinetics. We define a polarization for the electron-transfer rate constant and show that it correlates with the strength of the acceptor QD circular dichroism (CD) spectrum. These results 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.

Directing Charge Transfer in Quantum Dot Assemblies

Journal Article Bloom, Brian P. ; Liu, Ruibin ; Zhang, Peng ; ... - Accounts of Chemical Research

The optical and electronic properties of semiconductor quantum dots (QDs) make them attractive candidates for applications in photovoltaics, spintronics, photocatalysis, and optoelectronics. Understanding how to control the flow of charge in QD assemblies is essential for realizing novel applications. This Account explores some unique characteristics of charge transport in QD dyads, triads, and their assemblies. The emerging features of these assemblies that provide new opportunities to manipulate charge flow at the nanoscale are (1) cascading energy landscapes and band offsets to inhibit charge recombination, (2) electrostatic fields that direct charge flow through QD–QD and QD-conjugated polymer junctions, and (3) QDmore »« less

Ligand Coverage and Exciton Delocalization Control Chiral Imprinting in Perovskite Nanoplatelets

Journal Article Georgieva, Zheni N. ; Zhang, Zhendian ; Zhang, Peng ; ... - Journal of Physical Chemistry. C

Chiral perovskites have generated significant recent interest, yet little is known about how their chiro-optical properties arise. In this study, chiral methylammonium lead halide perovskite nanoplatelets (NPLs) with varied halide and ligand compositions are prepared using direct synthetic methods. Circular dichroism (CD) and ¹H NMR studies find a non-linear relationship between the chiroptical properties and the ratio of chiral phenylethylammonium (PEA) to achiral octylamine (OA) ligands on the NPL surface. We use density functional theory (DFT) computations and a chiral imprinted particle-in-a-box model to rationalize the experimentally observed CD spectra and find that the saturation point of the induced chiralitymore »« less

Controlling the Electron-Transfer Kinetics of Quantum-Dot Assemblies

Journal Article Liu, Ruibin ; Bloom, Brian P. ; Waldeck, David H. ; ... - Journal of Physical Chemistry. C

Electron transfer theory is used to investigate the size-dependence of electron transfer (ET) between dithiol-bridged quantum dots (QDs) and make predictions that can be tested experimentally. Electronic couplings, electronic densities of states, and reaction-free energies are all found to be size-dependent and to influence the ET rates. As the acceptor QD radius grows at fixed edge-to-edge donor–acceptor distance, the reaction-free energy becomes more negative. As a result, both electron and hole transfer rates show a peak as a function of acceptor radius for donor radii ranging from 9.5 to 21.5 Å; however, this rate maximum as a function of radiusmore »« less

Chiral Perovskite Nanoplatelets with Tunable Circularly Polarized Luminescence in the Strong Confinement Regime

Journal Article Cao, Qinxuan ; Song, Ruyi ; Chan, Christopher C. S. ; ... - Advanced Optical Materials

Abstract Chiral perovskite nanocrystals have emerged as an interesting chiral excitonic platform that combines both structural flexibility and superior optoelectronic properties. Despite several recent demonstrations of optical activity in various chiral perovskite nanocrystals, efficient circularly polarized luminescence (CPL) with tunable energies remains a challenge. The chirality imprinting mechanism as a function of perovskite nanocrystal dimensionality remains elusive. Here, atomically thin inorganic perovskite nanoplatelets (NPLs) are synthesized with precise control of layer thickness and are functionalized by chiral surface ligands, serving as a unique platform to probe the chirality transfer mechanism at the organic/perovskite interface. It is found that chirality ismore »« less

Electron-donating functional groups strengthen ligand-induced chiral imprinting on CsPbBr3 quantum dots

Journal Article Dunlap-Shohl, Wiley A. ; Tabassum, Nazifa ; Zhang, Peng ; ... - Scientific Reports

Abstract Chiral perovskite nanoparticles and films are promising for integration in emerging spintronic and optoelectronic technologies, yet few design rules exist to guide the development of chiral material properties. The chemical space of potential building blocks for these nanostructures is vast, and the mechanisms through which organic ligands can impart chirality to the inorganic perovskite lattice are not well understood. In this work, we investigate how the properties of chiral ammonium ligands, the most common organic ligand type used with perovskites, affect the circular dichroism of strongly quantum confined CsPbBr ₃ nanocrystals. We show that aromatic ammonium ligands with strongermore »« less
