Series of quinolone C3-substituted pyrazolines, isoxazolines, pyridines and pyrimidines were synthesized in good yields by the cyclocondensation reactions of 1, 2-unsaturated ketones and hydrazines, hydroxylamine hydrochloride and dimedone respectively. The quinolone derivatives (3, 5 and 7) were synthesized and further studied for their photophysical properties. High absorption and quantum yield are found for N1-phenyl and C3,4-dimethoxy substituents on phenyl ring (3h). Energy optimization by PM6 methods showed high stability required for selection of suitable candidates to be use as future blue emitters.
通过 1、2-不饱和酮与肼类、盐酸羟胺和二甲酮的环缩合反应,分别合成了一系列喹诺酮 C3 取代的吡唑啉类、异噁唑啉类、吡啶类和嘧啶类化合物,收率良好。合成了喹诺酮衍生物(3、5 和 7),并进一步研究了它们的光物理性质。苯环上的 N1-苯基和 C3,4-二甲氧基取代基具有较高的吸收率和量子产率(3h)。通过 PM6 方法进行的能量优化显示,这些化合物具有很高的稳定性,可用于选择合适的候选化合物作为未来的蓝色发光体。
