From the perspective of applied science, methods that allow the simple construction of versatile quantum dots (QDs)-loaded gels are highly desirable. In this work, we report the self-healing assembly methods for various fluorescent QDs-loaded gels. Firstly, we employed horizontal frontal polymerization (FP) to fabricate self-healing gels within several minutes using a rapid and energy-saving means of preparation. The as-prepared gels showed pH sensitivity, satisfactory mechanical properties and excellent self-healing properties and the healing efficiency reached 90%. The integration of the QDs with the gels allowed the generation of fluorescent composites, which were successfully applied to an LED device. In addition, by using the self-healing QDs-loaded gels as building blocks, the self-healing assembly method was used to construct complex structures with different fluorescence, which could then be used for sensing and encoding. This work offers a new perspective on constructing various fluorescent assemblies by self-healing assembly, and it might stimulate the future application of self-healing gels in a self-healing assembly fashion.
从应用科学的角度来看，能够简单构建多功能量子点（QD）负载凝胶的方法是非常理想的。在这项工作中，我们报告了用于各种荧光量子点负载凝胶的自愈合组装方法。首先，我们采用水平前沿聚合（FP）在几分钟内使用快速且节能的制备方法制造出自愈合凝胶。所制备的凝胶表现出pH敏感性、令人满意的机械性能和优异的自愈合性能，愈合效率达到90%。量子点与凝胶的整合使得能够生成荧光复合材料，该复合材料已成功应用于发光二极管（LED）器件。此外，通过将自愈合量子点负载凝胶用作构建单元，自愈合组装方法被用于构建具有不同荧光的复杂结构，进而可用于传感和编码。这项工作为通过自愈合组装构建各种荧光组件提供了新的视角，并且可能会推动自愈合凝胶以自愈合组装方式在未来的应用。
