摘要

在微波辅助下，姜黄素与多种氨基酸发生缩合反应，合成了一系列新型碳化聚合物点，并对其进行了表征。更引人注目的是，由姜黄素和左旋/右旋天冬氨酸制备的碳化聚合物点都能在水溶液和掺杂聚乙烯吡咯烷酮中发出强烈的白光。在驱动电流为 0.12 A 时，基于 L-Asp-CPD/PVP 和 D-Asp-CPD/PVP 的白光发光二极管的 CIE 坐标分别为 (0.36, 0.34) 和 (0.38, 0.32)，CRI 分别为 84.9 和 89.7，CCT 分别为 4385 K 和 3410 K。在工作时间为 5 小时、驱动电流为 0.02 A 时，D-Asp-CPD 衍生的 LED 的稳定性优于 L-Asp-CPD。

White light emission from chiral carbonized polymer dots

A series of novel carbonized polymer dots have been synthesized and characterized via the condensation reaction between curcumin and various amino acids with the assistance of microwave. More strikingly, both CPDs prepared from curcumin and L/D-aspartic acid can emit strong white light in aqueous solution and in doped polyvinylpyrrolidone. The white light emitting diodes based on L-Asp-CPD/PVP and D-Asp-CPD/PVP exhibit the CIE coordinates of (0.36, 0.34) and (0.38, 0.32) at the drive current of 0.12 A, CRI of 84.9 and 89.7, and CCT of 4385 K and 3410 K, respectively. The stability of LED derived from D-Asp-CPD was better than that from L-Asp-CPD at operational time of 5 h and the driven current of 0.02 A.
