Description

Description générale

Azobenzene is a chromogen and an azo compound that exhibits trans/cis isomerism yielding isomers that differ in color. It is a simple azoarene compound that shows cis-trans isomerization around the azo bond in response to light.

Application

Azobenzene and its derivatives have multiple applications in the field of mechanical and optical materials, in photopharmacology, and molecular photo-switches including in biological probes.
As human tissue is translucent to red and near-infrared light but opaque to blue and UV light, Azobenzene is important in medicine and photopharmacology for applications that involve shifting the absorptions of both trans and cis isomers of azobenzene to longer wavelengths.
