Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

Angewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Moiré Folded Helical States at the Interfaces of Heterostructures

Advanced Physics Research, EarlyView.
This manuscript explores a minimal ladder model of a graphene‐topological‐insulator heterostructure where moiré superlattices modulate Rashba spin‐orbit coupling. The study reveals that SOC lifs spin degeneracy, halves spectral periodicity, and induces “helicity fragmentation” across moiré minibands.

Guiding and Manipulating Light Fields in Microstructured Liquid Crystals

Advanced Physics Research, EarlyView.
This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...
