The indication of information in materials is widely used in our daily life, and optical encoding materials are ideal for information loading due to their easily readable nature and adjustable optical properties. However, most of them could only indicate one type of information, either changing or unchanging due to the mutual interference. Inspired by firefly, we present a non-interfering bipolar information indication system capable of indicating both changing and unchanging information. A photochemical afterglow material is incorporated into the photonic crystal matrix through a high-throughput technique called shear-induced ordering technique, which can efficiently produce large-area photonic crystal films. The indication of changing and unchanging information is enabled by two different utilizations of white light by the afterglow material and photonic crystals, respectively, which overcome the limitations of mutual interference. As a proof of concept, this system is used to indicate the changing photodegradation level of mecobalamin (a photosensitive medicine) and unchanging intrinsic drug information with anti-counterfeiting functionality, which is a promising alternative to instantly ascertain the efficacy of medicine at home where conventional assays are impractical.
材料中的信息指示在我们的日常生活中被广泛使用，而光学编码材料因其易于读取的特性和可调节的光学性质，是信息加载的理想选择。然而，它们中的大多数由于相互干扰，只能指示一种类型的信息，无论是变化的还是不变的。受萤火虫启发，我们提出了一种能够同时指示变化信息和不变信息的无干扰双极信息指示系统。一种光化学余辉材料通过一种名为剪切诱导有序技术的高通量技术被纳入光子晶体基质中，该技术能够高效地制备大面积光子晶体薄膜。余辉材料和光子晶体分别通过对白光的两种不同利用来实现变化信息和不变信息的指示，这克服了相互干扰的限制。作为概念验证，该系统用于指示甲钴胺（一种光敏药物）变化的光降解水平和具有防伪功能的不变的药物固有信息，这是在传统检测方法不实用的家庭环境中即时确定药物疗效的一种有前途的替代方法。
