, p. 245 - 250 (2015)
A search for colorants capable of reducing the surface energy of synthetic fibers as well as adding color led to the synthesis and characterization of the repellency behavior of dyes such as 4-N,N-diethylamino-4′-tridecafluorohexylazobenzene. Unexpectedly

Fluoroalkylation reactions of (hetero)aromatics have been accomplished through the low-power illumination from red LEDs (λmax = 635 nm) of commercially available perfluoroalkyl iodides RF-I and phthalocyanine zinc salt as photocatalyst in MeCN?:?DMF solvent mixture. This methodology has been extended to the perfluorobutylation of sulfides. As far as we are concerned, this is the first report on a perfluoroalkylation reaction of (hetero)aromatics and sulfides under red-light photocatalysis.

Paragraph 0046-0048, (2019/12/25)
The invention discloses rapid-response photoisomerization 4-perfluoroalkyl azobenzene allyl ether and a preparation method thereof. The general structural formula of 4-perfluoroalkyl azobenzene allyl ether is shown in the Specification. The preparation method includes the following steps: dissolving the starting compounds, 4-iodoaniline and fluorine-containing alkyl iodide, into a high boiling point solvent, and under the protection of nitrogen, heating, and catalyzing the solvent by copper powder to obtain fluoroalkyl aniline; after diazotizing fluoroalkyl aniline using hydrochloric acid/nitrite system at a temperature of 0-5 DEG C, enabling the diazotized solution to react with the phenol alkaline solution to obtain perfluoroalkyl azo phenol; under the protection of nitrogen, heating perfluoroalkyl azo phenol and 3-bromopropylene in an anhydrous and oxygen-free polar solvent under a weak base condition to obtain 4-fluoroalkyl azobenzene propenyl ether. The fluorine-containing azobenzene compound photoisomerization provided by the invention can response rapidly, has an active functional group propenyl, is capable of participating in addition reactions or polymerization reactions, and can be applied widely.

The title compounds are obtained by direct hydrolysis of the corresponding 2/4-perfluoroalkyl-substituted anilines and anisoles by the system AcOH/HBr/H2O/Al2O3. A two-step preparation of 2/4-perfluoroacylanilines involves the treatment of the 2/4-perfluoroalkylaniline with sodium ethoxide followed by hydrolysis of the resultant diethyl acetal with hydriodic acid.

The compounds, 4-(nonafluorobutyl)aniline, 4-(tridecafluorohexyl)aniline, and 4-(heptadecafluorooctyl)aniline were prepared by the reaction of corresponding perfluoroalkyl iodide with 4-iodoaniline in the presence of copper bronze.Six azobenzene derivatives (4-(4-fluorophenylazo)phenol, F(C6H4)N=N(C6H4)OH (1) (C6H4=p-phenylene), 4-(trifluoromethylphenylazo)phenol, CF3(C6H4)N=N(C6H4)OH (2), 4-(4-heptafluoropropylphenylazo)phenol, C3F7(C6H4)N=N(C6H4)OH (3), 4-(4-nonafluorobutylphenylazo)phenol, C4F9(C6H4)N=N(C6H4)OH (4), 4-(4-tridecafluorohexylphenylazo)phenol, C6F13(C6H4)N=N(C6H4)OH (5), and 4-(4-heptadecafluorooctylphenylazo)phenol, C8F17(C6H4)N=N(C6H4)OH (6)) were prepared by the usual diazo coupling reactions using 4-(perfluoroalkyl)aniline and phenol.The monomolecular film formations of the azobenzene derivatives at the air/water interface were investigated by surface pressure measurements to be dependent on the fluoroalkyl chain length (n).The compounds 5 (n=6) and 6 (n=8) formed stable monomolecular films at the air/water interface.
