quinoxaline derivatives were examined and compared with isoluminol and luminol. These compounds produced chemiluminescence by reaction with hydrogen peroxide in the presence of potassium hexacyanoferrate(III) in sodium hydroxide solution. The chemiluminescence intensities of these chemiluminophores were affected by the concentrations of hydrogen peroxide, potassium hexacyanoferrate(III) and sodium hydroxide
通过各种1,2-二酮与-4,5-二氨基邻苯二甲酸二甲酯(5)和-3,4-二氨基邻苯二甲酸二甲酯(5')的反应合成了含有喹喔啉部分的新型鲁米诺和异鲁米诺相关化合物。在不同极性的溶剂中研究了染料的UV-Vis吸收和发射光谱,这些化合物显示出溶剂氟特性。检查了基于异鲁米诺和鲁米诺的喹喔啉衍生物的化学发光性质,并将其与异鲁米诺和鲁米诺进行了比较。在六氰合铁酸钾(III)的氢氧化钠溶液中,这些化合物通过与过氧化氢反应而产生化学发光。这些化学发光体的化学发光强度受过氧化氢,六氰合铁酸钾(III)和氢氧化钠浓度的影响。发现这些喹喔啉衍生物产生化学发光,范围为3.2–7.3,强度比异鲁米诺和鲁米诺分别高0.57–1.7倍。
