Abstract

Amorphous purely organic phosphorescence materials with long-lived and color-tunable emission are rare. Herein, we report a concise chemical ionization strategy to endow conventional poly(4-vinylpyridine) (PVP) derivatives with ultralong organic phosphorescence (UOP) under ambient conditions. After the ionization of 1,4-butanesultone, the resulting PVP-S phosphor showed a UOP lifetime of 578.36 ms, which is 525 times longer than that of PVP polymer itself. Remarkably, multicolor UOP emission ranging from blue to red was observed with variation of the excitation wavelength, which has rarely been reported for organic luminescent materials. This finding not only provides a guideline for developing amorphous polymers with UOP properties, but also extends the scope of room-temperature phosphorescence (RTP) materials for practical applications in photoelectric fields.

具有颜色可调超长有机磷光的非晶态离子聚合物

具有长寿命和颜色可调的非晶纯有机磷光材料是罕见的。在此，我们报道了一种简明的化学电离策略，使传统的聚(4-乙烯基吡啶)(PVP)衍生物在环境条件下具有超长有机磷光(UOP)。经1,4-丁烷磺酮电离后得到的PVP- s荧光体UOP寿命为578.36 ms，是PVP聚合物本身的525倍。值得注意的是，随着激发波长的变化，观察到从蓝色到红色的多色UOP发射，这在有机发光材料中很少报道。这一发现不仅为开发具有UOP特性的非晶聚合物提供了指导，而且扩大了室温磷光(RTP)材料在光电领域的实际应用范围。
