Peroxyoxalate chemiluminescence (PO-CL) is one of the most popular cold light sources, yet the drawback of aggregation-caused quenching limits their use. Here, we report a new kind of efficient bifunctional emitter derived from salicylic acid, which not only exhibits typical aggregation-induced emission (AIE) character but also has the ability to catalyze the CL process under basic conditions based on base sensitivity. By taking advantage of these unique features, we successfully confine the CL process on the surface of solid bases and provide a high-contrast visualization of CL emission. This method allows most of the common basic salts like sodium carbonate to be invisible encryption information ink and PO-CL solution to be a decryption tool to visualize the hidden information. The current study opens up an appealing way for the development of multifunction CL emitters for information encryption and decryption applications.
过氧草酸酯化学发光（PO-CL）是最受欢迎的冷光源之一，但聚集引起的猝灭的缺点限制了它们的使用。在这里，我们报告了一种新型高效的双功能发射体，它源自水杨酸，不仅表现出典型的聚集诱导发光（AIE）特性，而且还具有在碱性条件下基于碱基敏感性催化 CL 过程的能力。利用这些独特的特性，我们成功地将 CL 过程限制在固体碱的表面上，并提供了 CL 发射的高对比度可视化。该方法允许将大多数常见的碱性盐（如碳酸钠）作为不可见的加密信息墨水，将 PO-CL 溶液作为解密工具来可视化隐藏信息。目前的研究为开发用于信息加密和解密应用的多功能 CL 发射器开辟了一条有吸引力的途径。
