The azobenzene derivatives

SPIE Proceedings, 2015
Azobenzene derivatives constitute a group of dyes which have photochromic properties and have been investigated as promising systems for diverse applications in the unconventional optic area, their properties can be moulded with help of light.

Thermolysis of azobenzene

Russian Chemical Bulletin, 1993
Thermolysis of azobenzene in a melt and in solution results in the formation of aniline. The possible directions of the reaction are considered. Comparison of the enthalpies of the reaction proves that the cleavage of a π-bond in the N=N group to form a biradical intermediate is thermodynamically more favorable than that of a C-N π-bond.

Photodecomposition of azobenzenes

Journal of Chemical Technology and Biotechnology, 1980
AbstractUpon ultraviolet irradiation azobenzene and decafluoroazobenzene in cyclohexane and diethyl ether solutions decompose into phenylazo, phenylazomethylene and aniline radicals. The major products formed in cyclohexane solution are N‐cyclohexylaniline, N‐cyclohexylpentafluoroaniline, phenylazocyclohexane, pentafluorophenyl‐azocyclohexane, 1‐phenyl‐

Photoswitchable adhesives using azobenzene-containing materials.

Chemistry - An Asian Journal, 2019
Photoinduced reversible solid-to-liquid transitions of azobenzene-containing materials can control adhesion. Photoswitchable adhesives based on azobenzene-containing small molecules and polymers are under intense investigation.

Phenylation of azobenzene

Journal of the Chemical Society B: Physical Organic, 1970
The substituent effect of the phenylazo-group in homolytic phenylation has been measured with azobenzene as substrate and nitrobenzene as reference compound. Even after allowance for the large number of sites of substitution the phenylazo-group was shown to equal the nitro-group in its activating power.

Direct ortho-mercuration reactions of azobenzene and ortho-substituted azobenzenes

Journal of Organometallic Chemistry, 1976
Abstract The mercuration of azobenzene occurred exclusively in the ortho -position to yield 2-chloromercuriazobenzene and a mixture which on iodination gave 2,2'and 2,6-diiodoazobenzene. Ten other ortho -substituted azobenzenes were mercurated and mercuration was found to occur predominately in an ortho -position.
