摘要

超分子塑料（SPs）的创新发展被认为是全球为解决石油基塑料造成的环境污染问题所做的努力之一。传统的超分子塑料通常由于非共价键相对较弱而显示出较低的机械强度，并且缺乏适合实际应用的功能。为了克服这些局限性，我们在此报告了由新兴纳米粒子（即用脲基嘧啶酮基团修饰的碳化聚合物点（CPDs））组装而成的纳米胶体超分子塑料（NSPs）。这些 NSP 具有良好的机械性能、独特的光激活室温磷光（RTP）和出色的溶剂稳定性。值得注意的是，NSP 可循环使用，在多次使用后仍能保持其原有的机械性能和光激活 RTP。此外，通过在 NSP 中加入有机分子，还可实现多种颜色的光活化 RTP。我们展示了 NSP 在高级信息安全领域的概念验证应用。这项工作的成果为利用 CPD 组装功能材料铺平了道路，并将推动可持续应用的创新纳米材料的发展。

Mechanically Strong Nanocolloidal Supramolecular Plastics Assembled from Carbonized Polymer Dots with Photoactivated Room-Temperature Phosphorescence

The innovative development of supramolecular plastics (SPs) is recognized as one of the global efforts to address the environmental pollution caused by petroleum-based plastics. Traditional SPs usually show weak mechanical strength because of relatively weak noncovalent bonds and a lack of appropriate functions for practical applications. To overcome these limitations, we herein report nanocolloidal supramolecular plastics (NSPs) assembled from newly emerging nanoparticles, namely, carbonized polymer dots (CPDs) modified with ureido pyrimidinone groups. These NSPs display good mechanical properties, unique photoactivated room-temperature phosphorescence (RTP), and excellent solvent stability. Notably, NSPs are recyclable with maintenance of their original mechanics and photoactivated RTP after several usages. Furthermore, photoactivated RTP with multiple colors is achieved by incorporating organic molecules into NSPs. We show proof-of-concept applications of NSPs in high-level information security. The results in this work pave an avenue toward functional materials assembled from CPDs and will advance the development of innovative nanomaterials for sustainable applications.
