Collection: Azobenzenes [Photochromic Dyes]

Azobenzenes [Photochromic Dyes] — a collection of azobenzene compounds with alkoxy or methyl substituents that undergo reversible cis-trans isomerization upon light exposure, making them photochromic chromophores for optically responsive materials in liquid crystal systems and thin films.

Azobenzene derivatives such as 4,4'-bis(dodecyloxy)-3-methylazobenzene are used by functional materials researchers in the development of photoresponsive liquid crystals, molecular actuators, and light-switchable surfaces. Mannitol structures conjugated with azobenzene are also studied for self-assembly materials and optical data storage based on molecular conformational changes.

Product examples in this collection: TCI B4598 1440509-01-2 4,4'-Bis(dodecyloxy)-3-methylazobenzene, TCI B6252 2052287-45-1 (E)-4,4'-Bis(octyloxy)-3-methylazobenzene, TCI B4597 1627844-78-3 4,4'-Bis(decyloxy)-3-methylazobenzene, TCI H1452 1093077-77-0 1,2,3,4,5,6-Hexa-O-[11-[4-(4-hexylphenylazo)phenoxy]undecanoyl]-D-mannitol, TCI B4596 1440509-03-4 4,4'-Bis(hexyloxy)-3-methylazobenzene.

Pay attention to the position and type of substituents (alkoxy, methyl), which determine the isomerization wavelength and the thermal stability of the cis isomer, according to the requirements of the intended photoresponsive material application. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
