A novel photochromic azobenzene compound and its synthetic method

The invention provides a novel photochromic azobenzene compound and a synthesis method thereof and relates to a novel compound N-[4-[2-(4-methoxyphenyl) diazenyl] phenyl]-2-nitroaniline with a photochromic property and a synthesis method of the novel compound. The synthesis method comprises diazonium coupling reaction and coupling reaction between aromatic amine and aromatic halides. According to the invention, coupling reaction conditions of aromatic amine and aromatic halides are very simple, to be specific, only alkali metal fluorides with equal molar mass are added into reaction liquid, and reflux is carried out at 130 DEG for 3 h; a solvent is not required to be subjected to anhydrous anaerobic treatment, that reaction is carried out under nitrogen or argon atmosphere is not required, no side reaction is generated, aftertreatment of the product is simple, the conversion rate is higher, the yield of the target product is 48-74%, in addition, equipment adopted by the invention is relatively simple, the cost is low, and obvious economic benefits and environment-protection benefits are realized. The defects, in the prior art, that coupling reaction between aromatic amine and aromatic halides can be carried out at high temperature, with existence of inorganic base and under anhydrous anaerobic inert atmosphere usually, the reaction time is long, side reaction is multiple and the yield is low are overcome.

Rapid and direct spectrophotometric method for kinetics studies and routine assay of peroxidase based on aniline diazo substrates

Peroxidases are ubiquitous enzymes that play an important role in living organisms. Current spectrophotometrically based peroxidase assay methods are based on the production of chromophoric substances at the end of the enzymatic reaction. The ambiguity regarding the formation and identity of the final chromophoric product and its possible reactions with other molecules have raised concerns about the accuracy of these methods. This can be of serious concern in inhibition studies. A novel spectrophotometric assay for peroxidase, based on direct measurement of a soluble aniline diazo substrate, is introduced. In addition to the routine assays, this method can be used in comprehensive kinetics studies. 4-[(4-Sulfophenyl)azo]aniline (λ max = 390 nm, ? = 32 880 M?1 cm?1 at pH 4.5 to 9) was introduced for routine assay of peroxidase. This compound is commercially available and is indexed as a food dye. Using this method, a detection limit of 0.05 nmol mL?1 was achieved for peroxidase.
