Exempel på hur man kan använda AZOBENZENE i en mening

• Methyl orange is an azobenzene derivative that can be formed from dimethylaniline and sulfanilic acid, first through a diazonium salt formation with the sulfanilic acid, followed by a nucleophilic attack from the dimethylaniline and rearomatization.
• Several examples of photochromic compounds include: azobenzene, spiropyran, merocyanine, diarylethene, spirooxazine, fulgide, hydrazone, nobormadiene, thioindigo, acrylamide-azobenzene-quaternary ammonia, donor-acceptor Stenhouse adducts, stilbene, etc.
• Over time, the monomeric material dimerizes to give the parent azobenzene dioxide as a pale yellow solid.
• By incorporation of an azobenzene unit, a photoswitchable version of capsazepine (AC4) was developed in 2013 that allows for optical control of TRPV1 channels with light.
• Also in 1980 Shinkai throws out the anthracene unit as photoantenna in favor of an azobenzene moiety and for the first time envisions the existence of molecules with an on-off switch.
• For example, he could address azobenzene by an electric field or by electron/hole catalysis, establish ortho-fluoroazobenzenes as solely visible light switchable and thermally stable photoswitches, develop extremely fatigue resistant diarylethenes as well as photoswitches based on acylhydrazones and indigos, and moreover design dihydropyrenes that allow for single NIR photon switching.
• Specifically, a synthetic short peptide was alkylated with azobenzene crosslinkers and used to photo-stimulate mitochondrial membrane depolarization and cytochrome c release in permeabilized cells, initiating the intrinsic apoptosis pathway.
• There are a number of similar photoswitches which isomerize between E and Z configurations across an azo group (for instance, azobenzene and azopyrazole) or an ethylene bridge (for instance, stilbene and hemithioindigo).
• Fuchter has also developed novel molecular photoswitches – molecules that can be cleanly and reversibly interconverted between two states using light – with a focus on heteroaromatic versions of azobenzene.
• In 2018, Wong and his research team developed a new sophisticated hydrogel system (using polyacrylamide polymers with azobenzene cross linker) with reversibly tuneable physical stiffness, controlled by either near-UV or blue light exposure which allow the control of stiffening of a cell's external environment via irradiating the hydrogel with specific wavelengths of light.
