Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics

open access: yesAdvanced Optical Materials, EarlyView.
Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.

Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics

open access: yesAdvanced Optical Materials, EarlyView.
Novel type of rubrene microcrystals in the orthorhombic phase are grown exhibiting spatial contrast in spectra and dynamics due to differences in unit cell orientation. Distinct zones selectively host redshifted luminescence band at ≈650 nm driven by high photon absorption.
