White-light-emitting materials and devices have attracted enormous interest because of their great potential for various lighting applications. We herein describe the light-emitting properties of a series of new difunctional organic molecules of remarkably simple structure consisting of two terminal 4-pyridone push-pull subunits separated by a polymethylene chain. They were found to emit almost "pure" white light as a single organic compound in the solid state, as well as when incorporated in a polymer film. To the best of our knowledge, they are the simplest white-light-emitting organic molecules reported to date.
白光发射材料和器件因其在各种照明应用中的巨大潜力而引起了极大的关注。在此，我们描述了一系列新型双功能有机分子的发光性质，这些分子具有非常简单的结构，由两个末端 4-吡啶酮推拉亚基通过亚甲基链隔开。它们被发现作为单一有机化合物在固态以及掺入聚合物膜中时发出几乎“纯”的白光。据我们所知，它们是迄今为止报道的最简单的白光发射有机分子。
