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.

Switching Quantum Interference in Phenoxyquinone Single Molecule Junction with Light
Nanomaterials, 2020 Quantum interference (QI) can lead to large variations in single molecule conductance. However, controlling QI using external stimuli is challenging. The molecular structure of phenoxyquinone can be tuned reversibly using light stimulus.

Spatially resolved ultrafast transport current in GaAs photoswitches [PDF]
, 2010 We apply a pump- and probe-scheme to coplanar stripline circuits to investigate the photocurrent response of GaAs photoswitches in time and space. We find a displacement current pulse, as reported earlier.

Advanced Optical Materials, EarlyView.Naphthopyran–benzophenone compounds can act simultaneously as photoinitiators and photochromic molecules for two‐photon polymerization. Using a single‐step process, liquid photoresist is encapsulated within polymerized 3D microstructures, preserving reversible UV–vis photochromism after fabrication.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
