Materials with lifetime-tunable room-temperature phosphorescence are fascinating for multiple encryption-decryption security applications. Herein, by introducing different halogen ions, that is, Cl, Br, and I, together with organic luminescent units to bond to a zinc center, three coordination polymers were hydro(solvo)thermally synthesized. The results show that three coordination polymers present room-temperature phosphorescence with different lifetimes. Furthermore, a multiple encryption-decryption system combining temporal and spatial resolution characteristics was designed.
具有寿命可调室温磷光的材料对于多种加密-解密安全应用具有吸引力。在此，通过引入不同的卤素离子，即Cl、Br和I，以及有机发光单元与锌中心结合，水（溶剂）热合成了三种配位聚合物。结果表明，三种配位聚合物呈现出具有不同寿命的室温磷光。此外，还设计了一种结合时间和空间分辨率特性的多重加密-解密系统。
