Nations, industries, and aspects of everyday life have undergone forgery and counterfeiting ever since the emergence of commercialization. Securing documents and products with anticounterfeit additives shows promise for authentication, allowing one to combat ever-increasing global counterfeiting. One most-used effective encryption strategy is to combine with optical-security markers on the required protection objects; however, state-of-the-art labels still suffer from imitation due to their poor complexity and easy forecasting, as a result of deterministic production. Developing advanced anticounterfeiting tags with unusual optical characters and further incorporating complex security features are desired to achieve multimodal, unbreakable authentication capacity; unfortunately, this has not yet been achieved. Here, we prepare a series of stable circularly polarized luminescence (CPL) materials, composed of toxicity-free, high-quality-emitting inorganic quantum dots (QDs) and liquid crystals, using a designed helical-coassembly strategy. This CPL system achieves a figure of merit (FM, assessing the performance of both luminescence dissymmetry and quantum yield) value of 0.39, fulfilling practical demands for anticounterfeiting applications. Based on these CPL structures, we produce a type of multimodal-responsive security materials (MRSMs) that exhibits six different stimuli-responsive modes, including light activation, polarization, temperature, voltage, pressure, and view angle. Thus, we show a proof-of-principle blockchain-like integrated anticounterfeiting system, allowing multimodal-responsive, interactive/changeable information encryption–decryption. We further encapsulate the obtained security materials into a fiber to expand our materials to work on flexible fabrics, that is, building an intelligent textile with a color-adaptable function along with environmental change.

多峰响应圆偏振发光安全材料
自从商业化出现以来，国家、工业和日常生活的各个方面都经历了伪造和伪造。使用防伪添加剂保护文件和产品的安全，显示出认证的希望，使人们能够打击不断增加的全球假冒行为。一种最常用的有效加密策略是在所需保护对象上结合光学安全标记；然而，由于确定性生产，最先进的标签由于复杂性差且易于预测，因此仍然受到模仿。需要开发具有不寻常光学字符的先进防伪标签，并进一步结合复杂的安全功能，以实现多模式、牢不可破的认证能力；不幸的是，这一目标尚未实现。在这里，我们采用设计的螺旋共组装策略制备了一系列稳定的圆偏振发光（CPL）材料，由无毒、高质量发射的无机量子点（QD）和液晶组成。该CPL系统的品质因数（FM，评估发光不对称性和量子产率的性能）值为0.39，满足防伪应用的实际需求。基于这些 CPL 结构，我们生产了一种多模态响应安全材料 (MRSM)，它表现出六种不同的刺激响应模式，包括光激活、偏振、温度、电压、压力和视角。因此，我们展示了一种类似区块链的原理验证集成防伪系统，允许多模式响应、交互式/可变信息加密解密。 我们进一步将获得的安全材料封装到纤维中，以将我们的材料扩展到柔性织物上，即构建具有随着环境变化而具有颜色适应功能的智能纺织品。
