We describe a systematic study of a series of eight blue light-emitting molecules which can be prepared in one step from inexpensive commercial starting materials. The relative luminescence quantum yield can be as high as 84% and the heterocycles are luminescent in the condensed state, either as solids or as oils, indicating that there is no self-quenching in this system. The last observation augurs well for these heterocycles being useful in the fabrication of deep blue light-emitting devices.
我们描述了一项对由廉价商用起始原料一步合成的一系列八种蓝光发光分子的系统研究。它们的相对发光量子产率可高达84%,这些
杂环化合物在凝缩状态下,无论是固体还是油状物中均能发光,这表明该体系中不存在自猝灭现象。最后一个观察结果预示着这些
杂环化合物在制作深蓝色发光器件方面具有应用价值。
