Solution Volume Effects on Spontaneous Chiral Symmetry Breaking of Sodium Chlorate Crystals

Su Yeon Bak et al.

Summary: We report the spontaneous chiral symmetry breaking in the evaporative crystallization of sodium chlorate by controlling the solution volume. The critical volume, below which complete chiral symmetry breaking occurs spontaneously, is determined. The explanation involves the rare probability of simultaneous formation of multiple nuclei in a small volume, depletion due to rapid consumption of surrounding sodium chlorate molecules during crystal growth, and secondary nucleation. This study offers an important methodology for studying chiral symmetry breaking behaviors in various chiral nanomaterials and organic molecules.

Parity Violation Energy Difference Calculation of Atropisomers

Dhanalakshmi Vadivel et al.

Summary: Enantiomers have different energies due to parity violation effects, but calculating these effects and their impact on the choice of one enantiomer in homochirality is still debated. This study focuses on the energy difference in atropisomers, which are stereoisomers characterized by rotation around one bond. Atropisomers may have a low energy barrier for interconversion, making them important in equilibrating enantiomers and selecting the most stable one. Additionally, extended structures like polymers or crystals with helical frameworks can contribute to the overall parity violation energy. The discussion here provides a qualitative model to predict the sign of local contributions of atoms based on the general structure of the final molecule.

Absolute asymmetric polymerizations in solution needing no physical chiral source

Guanwu Yin et al.

Summary: In this study, five types of absolute asymmetric polymerizations were achieved, resulting in soluble high molecular weight chiral polymers without the use of chiral compounds or circularly polarized light. This new mechanism provides clues for a better understanding of the origin of chirality in our world.

Toward Detection of the Molecular Parity Violation in Chiral Ru(acac)3 and Os(acac)3

Marit R. Fiechter et al.

Summary: This study presents a theory-experiment investigation on the helically chiral compounds Ru(acac)(3) and Os(acac)(3) as candidates for next-generation experiments in detecting molecular parity violation (PV) in vibrational spectra. By using relativistic density functional theory calculations, optimal vibrational modes with PV effects exceeding the projected instrumental sensitivity of the ultrahigh resolution experiment being constructed at the Laboratoire de Physique des Lasers in Paris by up to two orders of magnitude were identified. Preliminary measurements of the vibrational spectrum of Ru(acac)(3) were conducted as the initial steps towards the planned experiment.

Resilience of parity-violation-induced chiral selectivity to nonequilibrium temperature fluctuations in open systems

David Hochberg et al.

Summary: We investigate the sensitivity of chemical reactions, which can undergo spontaneous mirror symmetry breaking, to chiral bias in the presence of nonequilibrium temperature fluctuations. We derive a selectivity criterion and test it with simulations. The results show that the deterministic bias can either select the final stable chiral outcome or select one of two possible outcomes with an asymmetric statistical weighting, depending on the magnitudes of the bias and the temperature fluctuations. For larger temperature fluctuations, the bias loses its selectivity.

Possible chemical and physical scenarios towards biological homochirality

Quentin Sallembien et al.

Summary: The single chirality of biological molecules in terrestrial biology raises questions about its origin. This article explores the possibility of inducing a significant chiral bias from scratch and discusses various scenarios regarding the emergence of biological homochirality. The review critically examines different theories and experimental evidence related to the induction and enhancement of enantiomeric excesses in organic molecules.

Spontaneous Deracemizations

Thomas Buhse et al.

Summary: Spontaneous deracemizations is a challenging topic in current chirality research, where achiral substances or racemic compositions are driven into an enantioenriched or homochiral state without any chiral inductors. Recent research shows that structural features alone are not enough to describe this process, and attention should be paid to the physicochemical origin and symmetry requirements of such processes.

Chemical Complexity and Consequent Homochirality from Weak Neutral Currents Acting upon Paramagnetic Enantiomers

Cheryl D. Stevenson et al.

Summary: The origin of chiral excess may have been initiated by one of the four universal forces or a statistical thermodynamic fluctuation in the confines of the electromagnetic force, ultimately involving parity violation by weak neutral currents. The weak force plays a significant role in biomolecular selection and the formation of homochirality, potentially serving as a crucial origin of chirality.

Spontaneous and induced chiral symmetry breaking of stereolabile pillar[5]arene derivatives upon crystallisation

Haiying Wang et al.

Summary: Stereolabile pillar[5]arene (P[5]) derivatives were used as platforms to study chiral symmetry breaking during crystallisation due to their dynamic racemic mixtures in solution. Crystal enantiomeric excess of a conglomerate-forming P[5] derivative can be obtained without external chiral entities through handpicking and Viedma ripening, while the handedness of P[5] derivative crystals can be directed and subsequently inverted in a highly controllable manner in the presence of optically-active solvents and chiral guests like ethyl d/l-lactate.
