Organic materials with long‐lived, color‐tunable phosphorescence are potentially useful for optical recording, anti‐counterfeiting, and bioimaging. Herein, we develop a series of novel host–guest organic phosphors allowing dynamic color tuning from the cyan (502 nm) to orange red (608 nm). Guest materials are employed to tune the phosphorescent color, while the host materials interact with the guest to activate the phosphorescence emission. These organic phosphors have an ultra‐long lifetime of 0.7 s and a maximum phosphorescence efficiency of 18.2 %. Although color‐tunable inks have already been developed using visible dyes, solution‐processed security inks that are temperature dependent and display time‐resolved printed images are unprecedented. This strategy can provide a crucial step towards the next‐generation of security technologies for information handling.

适用于可印刷和可书写安全油墨的大范围可调节颜色的有机磷光材料。

具有长寿命，颜色可调磷光的有机材料可能对光学记录，防伪和生物成像有用。本文中，我们开发了一系列新颖的主体-客体有机荧光粉，可以从青色（502 nm）到橙红色（608 nm）进行动态颜色调节。客体材料用于调节磷光颜色，而主体材料与客体相互作用以激活磷光发射。这些有机磷光体的超长寿命为0.7 s，最大磷光效率为18.2％。尽管已经使用可见染料开发了可调色油墨，但是与温度相关并显示时间分辨的印刷图像的溶液处理安全油墨是前所未有的。
