Multi-functional switches of ditopic ligands with azobenzene central bridges at a molecular scale

Nanoscale, 2019
This paper reports multi-functional switches from a ditopic ligand bpy-azo-bpy. The molecule can adopt a cis -to- trans isomerization at the bipyridine terminals and can switch between their TRANS and

QM/MM surface-hopping dynamics of a bridged azobenzene derivative

Physical Chemistry Chemical Physics, 2013
Ethylene-bridged azobenzene (diazocine) has been shown to have superior photochemical properties. So far, however, experimental and theoretical quantum yields did not match, not even qualitatively. Here, a large-scale QM/MM surface-hopping study of this molecule is presented.

Photochromic Molecular Gyroscope with Solid State Rotational States Determined by an Azobenzene Bridge

The Journal of Organic Chemistry, 2014
We describe the synthesis, characterization, photochemical isomerization, and rotational dynamics of a crystalline molecular gyroscope containing an azobenzene bridge (trans-2) that spans from one end of the stator to other, with the intention of exploring its function as a molecular brake.

A new series of azobenzene-bridged metal-free organic dyes and application on DSSC

Dyes and Pigments, 2017
Abstract A series of novel azobenzene-based dyes were designed and synthesized using azobenzene as the π-spacer unit to connect diarylamino and cyanoacetic acids for construction of the D–π–A conformation. The introduction of a thienyl into the anchor group (A) could lead to a red-shift in the absorption spectra and λonset of the dyes.

Optical Control of Insect Behavior and Receptors with Azobenzene-Bridged Fipronil and Imidacloprid

Journal of Agricultural and Food Chemistry
Photopharmacology can be implemented in a way of regulating drug activities by light-controlling the molecular configuations. Three photochromic ligands (PCLs) that bind on one or two sites of GABARs and nAChRs were reported here. These multiphoton PCLs, including FIP-AB-FIP, IMI-AB-FIP, and IMI-AB-IMI, are constructed with an azobenzene (AB) bridge ...

A Novel Infinite 1-D Chain of Silver(I) Bridged by trans-Azobenzene

Monatshefte fuer Chemie/Chemical Monthly, 2000
The self-assembly of Ag[BF4] with trans-azobenzene in dichloromethane yields a new coordination polymer ([Ag(μ-trans-azobenzene)H20][BF4]) n which was characterized by X-ray single crystal diffraction. The crystal consists of 1-D zigzag cationic chains made up from [Ag(H20)]+ units linked by trans-azobenzene bridges and BF 4 − anions.

An Azobenzene‐Bridged Nonporous Adaptive Framework Enables Photo‐Regulated Desorption of Iodine

Angewandte Chemie
Abstract Adsorption is one of the most convenient and efficient techniques for capturing and enriching various molecules. However, current strategies for the absorbent regeneration still face the challenges of labor‐intensive and/or environmentally unfriendly procedures.

Photocontrolled chiroptical switch based on the self-assembly of azobenzene-bridged bis-tryptophan enantiomers

Journal of Colloid and Interface Science
Chirality dynamic tuning plays fundamental roles in chemistry, material science and biological system. Herein, a pair of azobenzene-bridged bis-tryptophan enantiomers (Azo-di-d/l-Trp) were designed and synthesized via simple reactions. With the fuel of glucono-δ-lactone (GdL), releasing protons during its hydrolysis, the alkaline solution of Azo-di-d/l-
