Long‐persistent luminescence (LPL) materials have a wide range of applications, such as in architectural decorations, safety signs, watch dials, and glow‐in‐the‐dark toys. Present LPL materials based on inorganics must be processed into powders and blended with polymer matrices before use. However, micropowders of inorganic LPL materials show poor compatibility with common polymers, limiting the mechanical properties and transparency of the composites. Here, a polymer‐based organic LPL (OLPL) system that is flexible, transparent, and solution processable is reported. Following low‐power excitation at room temperature, this polymer‐based OLPL system exhibits LPL after phosphorescence from the donor.

柔性和透明掺杂聚合物产生的有机持久发光

持久发光（LPL）材料具有广泛的应用，例如在建筑装饰，安全标志，手表表盘和黑暗中发光的玩具中。现有的基于无机物的LPL材料必须在使用前加工成粉末并与聚合物基体混合。但是，无机LPL材料的微粉与普通聚合物的相容性较差，从而限制了复合材料的机械性能和透明性。此处报道了一种基于聚合物的有机LPL（OLPL）系统，该系统灵活，透明且可溶液处理。在室温下低功率激发后，这种基于聚合物的OLPL系统在施主发出磷光后显示出LPL。
