3-Cyano-4,6-dimethyl-2-pyridone and 3-cyano-4-methyl-6-phenyl-2-pyridone were synthesized effectively by the reaction of readily available 1,3-diketone and malononitrile directly and in good yield. Upon photoexcitation, 3-cyano-4-methyl-6-phenyl-2-pyridone in ethanol shows strong blue emission. The ground- and excited-state geometries, charge distributions, and excitation energies of 2-pyridone derivatives were evaluated by ab initio calculations. Organic light-emitting diodes (OLED) made using 3-cyano-4-methyl-6-phenyl-2-pyridone as dopant showed blue light emission with a maximum electroluminescence (EL) emission at around 456 nm.
3-氰基-4,6-二甲基-2-吡啶酮和 3-氰基-4-甲基-6-苯基-2-吡啶酮可由易得的 1,3-二酮和丙二腈直接反应以较好的收率有效合成。3-氰基-4-甲基-6-苯基-2-吡啶酮在乙醇中光照激发时表现出强蓝色发射。通过从头算计算评估了 2-吡啶酮衍生物的基态和激发态几何形状、电荷分布和激发能。以 3-氰基-4-甲基-6-苯基-2-吡啶酮为掺杂剂的有机发光二极管（OLED）表现出蓝色电致发光（EL）发射，最大发射波长在 456nm 左右。
