Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals
Angewandte Chemie, EarlyView.Light‐responsive ferroelectric nematics are achieved by molecularly matching azobenzene photo‐switches to the polar packing motif of DIO. This design yields intrinsically photo‐responsive ferroelectric nematic mesogens and optically addressable DIO blends, in which light reversibly modulates spontaneous polarization and switches between high‐ and low ...

Anethole Isomerization and Dimerization Induced by Acid Sites or UV Irradiation
Molecules, 2010 The formation of cis-anethole and various dimers as a result of the exposure of trans-anethole to microporous solid acids (dealuminated HY zeolites), or UV-Vis irradiation was established by means of high resolution gas chromatography coupled to mass ...

Multi-state Photoswitching in Thienoquinoid-Based Fluorescent Trithiophenes. [PDF]
ChemistryA methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.

Fundamental limitations on photoisomerization from thermodynamic resource theories [PDF]
, 2020 Small, out-of-equilibrium, and quantum systems defy simple thermodynamic expressions. Such systems are exemplified by molecular switches, which exchange heat with a bath. These molecules can photoisomerize, or change conformation, or switch, on absorbing

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Angewandte Chemie, EarlyView.A photoswitchable ligand was used to trigger conformational changes within the thrombin binding aptamer DNA G‐Quadruplex. These reversible ligand driven rearrangements were examined by time‐resolved NMR experiments to gain insight of the dynamic folding landscape of the G‐quadruplex.
