Graphene oxide catalyzed cis-trans isomerization of azobenzene

open access: yesAPL Materials, 2014
We report the fast cis-trans isomerization of an amine-substituted azobenzene catalyzed by graphene oxide (GO), where the amine functionality facilitates the charge transfer from azobenzene to graphene oxide in contrast to non-substituted azobenzene ...

Thermal stability improvement of azobenzene for the integration of photochemical and solar thermochemical energy conversion

open access: yesCase Studies in Thermal Engineering, 2023
Azobenzene is a typical photoisomerization material that is widely used in photochemical energy conversion. However, it's generally operated below 200 °C to avoid thermal decomposition.

Azobenzene dye-coupled quadruply hydrogen-bonding modules as colorimetric indicators for supramolecular interactions

open access: yesBeilstein Journal of Organic Chemistry, 2012
The facile coupling of azobenzene dyes to the quadruply hydrogen-bonding modules 2,7-diamido-1,8-naphthyridine (DAN) and 7-deazaguanine urea (DeUG) is described. The coupling of azobenzene dye 2 to mono-amido DAN units 4, 7, and 9 was effected by classic
