New Insights into Circularly Polarized Luminescence from Chromium(III) Spin-Flip Emitters
Circularly Polarized Luminescence (CPL) is emerging as a central tool for chiral photonics, enabling applications ranging from sensing and security inks to circularly polarized organic light-emitting diodes (OLEDs). While most highly developed CPL emitters are organic chromophores, lanthanide…

Spin Depolarization Mechanisms in Halide Perovskite Semiconductors
Halide perovskites (HPs) have developed into a promising material platform for investigating spin-optoelectronic applications. A key obstacle for real-world implementation, however, is achieving long electron spin lifetimes under ambient conditions. This review focuses on recent experimental…

When Chiral Molecular Design Shapes Light-Matter Interactions
This account highlights recent contributions from the Lacour group at the interface of chirality and light–matter interactions. Cationic helicenes, ylide-derived macrocycles and heterocycles, and boramidines are presented as complementary chiral platforms for tuning photophysical and chiroptical…

Raman Optical Activity (ROA) as an Emerging Standard in Molecular Chirality Measurements – A Perspective
Raman Optical Activity (ROA) is emerging as a powerful analytical tool for the characterization of molecular chirality, offering complementary capabilities to established chiroptical and crystallographic methods. In particular, its ability to probe molecules in solution and across a wide range of…

How Much Chirality is Enough?
Chirality is often discussed in chemistry as if it were a matter of degree: molecules are described as ‘more’ or ‘less’ chiral depending on the number of stereogenic elements, the magnitude of helical twist, or the extent of structural distortion. From a mathematical perspective, however, chirality…

Femto- and Attosecond Spectroscopy of Chiral Molecules
The capability of generating attosecond (10-18s) pulses of light in the extreme-ultraviolet domain through high-harmonic generation (HHG) has opened a broad range of possibilities in studying the fastest dynamics in matter. Notably, the creation of light pulses with tailored, time-dependent…

Molecular Chirality: From Structure to the Quantum Dynamics of Tunnelling, Parity Violation, a Molecular Quantum Switch and the Possible Astrophysical Detection of Homochirality as a Signature of Extraterrestrial Life
We briefly review the development of fundamental concepts in the current theory and experiments on molecular chirality, including the small effects arising from parity violating weak nuclear interaction. After a short summary of the history of theory and experiments in this field, we discuss the…

Natural, Unnatural Fluorine!
The rich variety of compounds containing the element fluorine, be it natural products, synthetic materials, or even minerals are well-suited for a critical discussion of the opposites ‘natural’ and ‘unnatural’.

Shining Light on Chiral Monolayer-protected Metal Clusters
Monolayer-protected metal clusters in the size range between about 10 to 300 metal atoms are a special class of materials with strongly size-dependent behaviour, which is mainly ascribed to discrete electronic energy levels. It was observed that certain sizes of metal clusters show exceptional…
