Organic Chemistry Frontiers, 2021
An azobenzene-bridged perylene bisimide cyclophane was designed and synthesized, which showed reversible fluorescence intensity switching under light-irradiation due to cooperative adjustments of PBI–PBI and PBI–Azo interactions.

Enhanced photoswitching of bridged azobenzene studied by nonadiabatic ab initio simulation
The Journal of Chemical Physics, 2012Photoisomerization of a bridged azobenzene derivative (AB-C2) is studied by nonadiabatic ab initio molecular dynamics simulation. The effect of the alkyl bridge linking the two phenyl rings on the Z → E and E → Z photoisomerization pathways and efficiencies is analyzed by detailed comparison to the unbridged parent compound. It is found that the bridge

QM/MM surface-hopping dynamics of a bridged azobenzene derivative
Physical Chemistry Chemical Physics, 2013Ethylene-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.

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.

Multi-functional switches of ditopic ligands with azobenzene central bridges at a molecular scale
Nanoscale, 2019This 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 CIS configurations at the central azobenzene unit by protonation or by light irradiation.

Abstract Two methods, Langmuir–Blodgett (LB) and self-assembly (SA), were used in the present work to fabricate certain interfacial structures for the study of long-range electron transfer. We have successfully constructed two different `bridges' for the interfacial electron transfer in azobenzene LB/SAM composite bilayer systems.

A Novel Infinite 1-D Chain of Silver(I) Bridged by trans-Azobenzene
Monatshefte fuer Chemie/Chemical Monthly, 2000The 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.

Abstract Binuclear chloro-bridged cyclopalladated azobenzenes [Pd(A)Cl]2 (A=ortho-metallated azobenzene or its derivatives) have been reacted with aqueous (aq.) AgNO3 followed by the addition of 2-hydroxypyridine (2-PyOH; donor centres of deprotonated form abbreviated N,O)/2-mercaptopyridine (2-PySH; donor centres of deprotonated form abbreviated N,S)
