长余辉发光（LPL）材料有着广泛的应用，如建筑装饰、安全标志、手表表盘和夜光玩具。目前基于无机物的LPL材料必须加工成粉末并在使用前与聚合物基体共混。然而，无机LPL材料的微粉与普通聚合物的相容性较差，限制了复合材料的机械性能和透明度。在这里，聚合物基有机LPL（OLPL）系统，是灵活的，透明的，和溶液加工的报告。在室温下低功率激发后，这种基于聚合物的OLPL系统在来自供体的磷光后表现出LPL。
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.
