The reaction of phenyl 9-acridinecarboxylate with an excess of peroxide ion in THF/water (67/33 mol %) leads to the emission of either bright yellow-green light or bright blue light, depending on the reaction conditions. The blue emission is favored by high concentrations of hydrogen peroxide and water, for example. 9-Acridinepercarboxylic acid is a common intermediate in the reactions. The light emitter
9-吖啶羧酸苯酯与过量的过氧化离子在 THF/水 (67/33 mol%) 中的反应导致发射亮黄绿色光或亮蓝色光,具体取决于反应条件。例如,高浓度的过氧化氢和水有利于蓝色发射。9-吖啶过羧酸是反应中常见的中间体。负责蓝色化学发光的发光体是吖啶酮,而负责黄绿色化学发光的发光体是吖啶酮的阴离子。碱浓度和溶剂组成对这两种发射体的相对比例的影响已经证明,与简单理论的预期相反,二氧杂环丁酮不是反应中的中间体。
