Tuning Circular Dichroism and Circularly Polarised Luminescence in Single Crystals of a Perylene Diimide Macrocycle

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,

Depth-resolved Mueller matrix polarimetry microscopy of the rat cornea

Biomedical Optics Express, 2020
Mueller matrix polarimetry (MMP) is a promising linear imaging modality that can enable visualization and measurement of the polarization properties of the cornea. Although the distribution of corneal birefringence has been reported, depth resolved MMP imaging of the cornea has not been archived and remains challenging.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, Volume 36, Issue 67, 20 August 2026.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Helically Flexible Boron‐Dipyrromethenes for Solution‐Processed Isotropic Films With Preserved Chiral Exciton Coupling

Aggregate, Volume 7, Issue 8, August 2026.
Accessible and chiroptically tunable helically chiral boron‐dipyrromethene dimer dyes enable the fabrication of solution‐processed isotropic neat thin films that retain sharp visible electronic circular dichroism signatures from solution. This platform establishes a direct molecule‐to‐material relationship and provides a robust foundation for the ...

The Combination of Chiral Assembly and Chiral Template Effects Boosts Circularly Polarized Luminescence of Perovskite Nanocrystals

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
We show that the hierarchical order of perovskite nanocrystal assemblies formed within a nanostructured, chal liquid‐crystalline template exhibits extremely high circularly polarized luminescence (CPL). This is due to the helical arrangement of PNCs in the template voids and capitalizes on the inherent electrooptic properties of the template ...
