Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

Angewandte Chemie, EarlyView.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

Coordination Programming of Photofunctional Molecules

Molecules, 2013
Our recent achievements relating to photofunctional molecules are addressed. Section 1 discloses a new concept of photoisomerization. Pyridylpyrimidine-copper complexes undergo a ring inversion that can be modulated by the redox state of the copper ...

UV and VUV spectroscopy and photochemistry of small molecules in a supersonic jet [PDF]

, 1990
UV and VUV absorption and emission spectroscopy is used to probe jet cooled molecules, free radicals, and clusters in the gas phase. Due to efficient cooling inhomogeneous effects on spectral line widths are eliminated. Therefore from these spectra, both

Kinetics of photoinduced ordering in azo-dye films: two-state and diffusion models

, 2008
We study the kinetics of photoinduced ordering in the azo-dye SD1 photoaligning layers and present the results of modeling performed using two different phenomenological approaches.

Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Solar Flow Synthesis of Polymer Nanoparticles: Scaling Local Experiments to Global Potential

Angewandte Chemie, EarlyView.
The large‐scale sunlight‐induced photochemical synthesis of polymer nanoparticles based on the Diels–Alder step‐growth polymerization of a bismaleimide and a difunctional o‐methylbenzaldehyde in a self‐built solar flow reactor is introduced. Furthermore, a framework is established to translate sunlight‐driven experimental results globally—validated in ...

Energy‐Efficient Bulk Photoalignment of Main‐Chain Liquid Crystalline Polymers Enabled by In Situ Monitoring

Advanced Functional Materials, EarlyView.
In situ monitoring of bulk photoalignment reveals how molecular weight, azobenzene content, cooling rate, and thickness govern ordering in main‐chain liquid crystalline polymers. Optimized copolymers exceed conventional thickness limits, maintaining stable alignment up to 130 µm with high energy efficiency and reversible optical patterning.
