Metathesis Cyclopolymerization Triggered Self-Assembly of Azobenzene-Containing Nanostructure

Molecules, 2020
Azobenzene (AB) units were successfully introduced into poly(1,6-heptadiyne)s in order to ensure smooth synthesis of double- and single-stranded poly(1,6-heptadiyne)s (P1 and P2) and simultaneously realize the self-assembly by Grubbs-III catalyst ...

A practical guide to versatile photoalignment of azobenzenes

, 2020
Photoalignment refers to a technique for the definition of the orientation of liquid crystals using light. The approach is based on the use of materials that either absorb or trigger a chemical reaction with an anisotropy that depends on the polarisation

Photonic crystal fibre as an optofluidic reactor for the measurement of photochemical kinetics with sub-picomole sensitivity [PDF]

, 2012
Photonic crystal fibre constitutes an optofluidic system in which light can be efficiently coupled into a solution-phase sample, contained within the hollow core of the fibre, over long path-lengths.

Halogen bonding enhances nonlinear optical response in poled supramolecular polymers [PDF]

, 2015
We demonstrate that halogen bonding strongly enhances the nonlinear optical response of poled supramolecular polymer systems. We compare three nonlinear optical chromophores with similar electronic structures but different bond-donating units, and show ...

Bis(imido)vanadium(V)-Catalyzed [2+2+1] Coupling of Alkynes and Azobenzenes Giving Multisubstituted Pyrroles.

Journal of the American Chemical Society, 2019
The combination of VCl3(THF)3 and N, N-bis(trimethylsilyl)aniline (1a) is an efficient catalyst for the [2+2+1] coupling reaction of alkynes and azobenzenes, giving multisubstituted pyrroles.

Conformational photoswitching of a synthetic peptide foldamer bound within a phospholipid bilayer [PDF]

, 2016
The dynamic properties of foldamers, synthetic molecules that mimic folded biomolecules, have mainly been explored in free solution.We report on the design, synthesis, and conformational behavior of photoresponsive foldamers bound in a phospholipid ...

Membrane Environment Enables Ultrafast Isomerization of Amphiphilic Azobenzene -INVITED [PDF]

EPJ Web of Conferences, 2020
We report on the isomerization dynamics of an amphiphilic azobenzene that dwells within the plasma membrane. We found that in aggregates formed in water, the isomerization reaction is hindered, while radiative deactivation is favoured.

Azobenzene photocontrol of peptides and proteins [PDF]

, 2016
The last few years have witnessed significant advances in the use of light as a stimulus to control biomolecular interactions. Great efforts have been devoted to the development of genetically encoded optobiological and small photochromic switches. Newly
