Azobenzene DNA Intercalator/Cyclodextrin Pseudo‐Rotaxane: From Photoswitchable Chirality and Fluorescence to DNA Melting Control

open access: yesChemistryOpen
Pseudo‐rotaxanes are reversibly interlocked molecules with at least one linear molecule threaded into a macrocycle and, contrary to rotaxanes, an advantageous ability to be dissociated.

Excited‐State Topology Modifications of the Dihydroazulene Photoswitch Through Aromaticity

open access: yesChemPhotoChem, 2019
The gain and loss of aromaticity plays a key role in organic chemistry and in the prediction of rate‐determining steps. Herein, we explore the concept of aromaticity in photoisomerization reactions.

Boosting Reversible Photocontrol of a Photoxenase by an Engineered Conformational Shift

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Photocontrol of enzymes with photoswitchable unnatural amino acids hitherto yielded only limited light‐regulation factors (LRFs). Here we boosted the LRF of an imidazole glycerol phosphate synthase variant from ∼15 to ∼100 in a semi‐rational design approach and unraveled the mechanistic fundamentals of this effect via biophysical and computational ...
