白色发光二极管（WLED）由于其潜在的技术应用而引起了人们的极大关注。在这项工作中，我们提出了两个新的锌（ii）蒽连接驱动的配位聚合物，表现出固有的白光发射。在室温下，发射覆盖整个可见光谱。宽带发射的色度坐标可以在外部刺激（包括热研磨和机械研磨）下进行调谐。所获得的配位聚合物材料在室温下发出适合于室内照明应用的“暖”白色光以及在低温下发出“冷”白色光。因此，良好定义的结构和机械可调的发射提供了一个很好的机会，实现其作为光电子学中的白色发射器的潜力。
White light-emitting diodes (WLEDs) have aroused great attention due to their potential technological applications. In this work, we present two new Zn(ii) anthracene-linker-driven coordination polymers that exhibit intrinsic white-light emission. The emission covers the whole visible spectrum at room temperature. The chromaticity coordinates of the broadband emission can be tuned under external stimuli, including thermal and mechanical grinding. The obtained coordination polymer materials emit a "warm" white light at room temperature suitable for indoor lighting applications as well as a "cold" white light at the cryogenic temperature. Hence, the well-defined structures and mechanically tunable emission provide an excellent opportunity for realizing their potential as white emitters in optoelectronics.
