Reversible and size-controlled assembly of reflectin proteins using a charged azobenzene photoswitch [PDF]
Disordered proteins often undergo a stimuli-responsive, disorder-to-order transition which facilitates dynamic processes that modulate the physiological activities and material properties of cells, such as strength, chemical composition, and reflectance.

Non‐Covalent Reversibly Photoconvertible Fluorescent Tags for Wash‐Free Protein Labeling
Advanced Science, EarlyView.FAST proteins combined with one or two fluorogens undergo reversible fluorescence switching or photoconversion through photoisomerization. At low fluorogen concentration and high light intensity, they act as negative or positive photoswitchers and photoconvertible tags, which are promising for discriminating FAST variants.

Predicting photoactivity in dithienylethene crystalline solids
IUCrJ, 2023 This commentary discusses the design of stimuli-responsive materials, specifically, light-responsive dithienylethene-based compounds. Recent progress in predicting photoactivity using a combination of theory and crystal structure landscape experiments is

Advanced Science, EarlyView.A dual‐track time‐resolved encryption strategy with independent information display during photo‐bleaching and thermal‐recovery stages has been realized through multiple temporal encoding units derived from orthogonal covalent‐noncovalent programming of donor–acceptor Stenhouse adduct photoswitching.

Chemical Switching Between B2N and B2C Homoaromaticity
Angewandte Chemie, EarlyView.We report the synthesis of homoaromatic 1‐aza‐2,4‐diazadiboretane with a bicyclic four‐membered NB2C motif and demonstrate experimentally and theoretically that the homoaromatic delocalization can also be chemically shifted from the B2N to the B2C moiety by deprotonation of the ring carbon atom.

Angewandte Chemie, EarlyView.A general strategy for 9,10‐phenanthrenequinone‐electron‐rich alkene (PQ‐ERA) photoclick reactions via triplet–triplet annihilation upconversion (TTA‐UC) under low‐intensity green light is reported. A TTA‐UC system of PdOEP (sensitizer) and DPA (annihilator) mixed with reactants generates UV/blue photons overlapping the absorption of PQ derivatives ...

Angewandte Chemie, EarlyView.This study investigates the influence of several substituents at different positions on photochemical and thermal properties of azobenzene‐based materials to provide valuable structure‐property relationships for the specific design of azobenzene‐based materials for future energy storage and phase change materials. ABSTRACT Understanding and translating

Synthesis and characterization of bis(4-amino-2-bromo-6-methoxy)azobenzene derivatives
Beilstein Journal of Organic Chemistry, 2019 Aminoazobenzene derivatives with four ortho substituents with respect to the N–N double bond are a relatively unexplored class of azo compounds that show promise for use as photoswitches in biology.

Comparative Analysis of Model‐Agnostic Explanation Methods in Materials Science
Advanced Intelligent Systems, EarlyView.To address the critical lack of explainable artificial intelligence (XAI) benchmarks in materials science, we present a quantitative and qualitative analysis of six XAI methods applied to molecular fingerprints. Our results reveal significant discrepancies in feature importance rankings, demonstrating that the chosen explanation approach introduces ...
