Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

open access: yesAngewandte 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 ...

Porphyrin‐Based Porous Materials for Antibacterial Applications

open access: yesAdvanced Science, EarlyView.
Porphyrin‐based porous materials have excellent photophysical properties and tunable structures for high‐efficiency antibacterial therapy. This review comprehensively discusses the structural design strategies and synthetic pathways of the four main types of porphyrin‐based porous materials, summarizes their cross‐domain antimicrobial applications, and

Time‐Resolved Multidimensional NMR Spectroscopy Reveals the Bifurcated Folding Pathway of a Thrombin‐Binding DNA G4–Azobenzene Derivative Complex

open access: yesAngewandte 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.

The absorption spectrum of cis-azobenzene

open access: yesPhotochemical & Photobiological Sciences, 2017
Azobenzene is a prototypical photochromic molecule existing in two isomeric forms, which has numerous photochemical applications that rely on a precise knowledge of the molar absorption coefficients (ε). Careful analysis revealed that the previously reported absorption spectra of the "pure" isomers were in fact mutually contaminated by small amounts of

Coherent Random Lasing Realized in Polymer Vesicles

open access: yesPhotonic Sensors, 2019
We have demonstrated the realization of a coherent vesicle random lasing (VRL) from the dye doped azobenzene polymer vesicles self-assembled in the tetrahydrofuran-water system, which contains a double-walled structure: a hydrophilic and hydrophobic part.

The D.C. polarography of azobenzene in pyridine

open access: yes, 1974
The d.c. polarography of azobenzene, sulphuric acid, acetic acid and mixtures of azobenzene with each of these acids in pyridine is reported. Azobenzene reduces in two one-electron steps, as is thecase in acetonitrile and dimethylformamide.
