固体白色发光材料的制备是一个具有挑战性的课题。在这项工作中,我们报告,结合聚集诱导发光和可逆配位聚合物的优点,固体白色发光薄膜的CIE坐标为(0.335,0.347)和外部量子效率高达11.74%,可以通过层层组装。特别地,R(红)G(绿色)B(蓝)元素的比例可以通过浓度来合理控制,这证明了可逆配位聚合物在功能材料的制造中的优势。固体薄膜的白色发射显示出优异的温度、pH和爆炸材料稳定性,但表现出对Cl 2的特异性检测,这表明其作为稳健的发光材料和化学传感器的巨大应用潜力。
Fabrication of solid white luminescent materials is a challenging topic. In this work we report that upon combining the advantages of aggregation induced emission and reversible coordination polymers, solid white luminescent films with the CIE coordinates of (0.335, 0.347) and external quantum efficiencies of up to 11.74% can be achieved via layer-by-layer assembly. In particular, the ratio of the R(red) G(green) B(blue) elements can be rationally controlled via concentration, demonstrating the advantage of reversible coordination polymers in the fabrication of functional materials. The white emission of the solid thin film displays excellent stability against temperature, pH, and explosion materials, but exhibits specific detection for Cl2, suggesting its great potential for application as both a robust luminescent material and a chemical sensor.
