Figure Lengend Snippet: Synthesis and characterization of BNN6. Note: (A) N,N'-di-sec-butyl-N,N'-dinitroso-1,4-phenylenediamine (BNN6) was synthesized by N,N'-di-sec-butylaminop-phenylenediamine (BPA) and NaNO 2 in hydrochloric acid solution. (B) Each peak of BNN6 was found in hydrogen nuclear magnetic resonance ( 1 H NMR). (C) With the 279.18 Da, in accordance with the molecular structure of BNN6 (301.16 is BNN6 plus one unit of sodium, 249.18 is BNN6 minus one unit of nitric oxide (NO), and 220.15 is the reactant BPA). The blue ray response of the synthesized BNN6 was confirmed through the color change of the solution (A, digital photo). The yellow solution of BNN6 became red after 45 seconds of irradiation by blue-ray.

Article Snippet: The structure of BNN6 was detected by hydrogen nuclear magnetic resonance (1 H NMR, Bruker Magnet System, Karlsruhe, Germany, 300 MHz/54 mm) and mass spectrum (MS, Waters LC-MS System, Milford, MA, USA) measurements.
