The development of highly luminescent perovskite quantum dots (PQDs) that can effectively merge with functional polymers is of paramount importance for next-generation flexible, printable, and wearable photonics and optoelectronics. Here, we report a universal strategy for the structural and functional integration of all-inorganic PQDs and polymers, which is enabled by judicious design and synthesis of photopolymerizable CsPbX3 (X = Cl, Br, I) QD inks with significantly enhanced environmental stability. High-resolution, multicolored fluorescent patterns are obtained by high-throughput photolithography and inkjet printing of highly stable, solution-processable, and photopolymerizable PQDs on surface-silanized polymers, which can be freely stretched and folded without delamination thanks to the robust covalent bonding at the organic-inorganic interface. As a proof-of-concept illustration, a light-driven self-deployable information display is demonstrated through covalent integration of photopolymerizable PQDs with a 4D-printed shape-morphing liquid crystal elastomer. This research will broaden the emerging applications of perovskite-polymer materials with unprecedented functionalities in diverse fields.

可聚合钙钛矿量子点与响应性聚合物的稳健结合使 4D 打印的可自部署信息显示成为可能
开发能够有效地与功能性聚合物融合的高发光钙钛矿量子点 (PQD) 对于下一代柔性、可印刷和可穿戴光子学和光电子学至关重要。在这里,我们报告了一种全无机 PQD 和聚合物的结构和功能整合的通用策略,这是通过可光聚合的 CsPbX 3的明智设计和合成实现的(X = Cl, Br, I) QD 墨水具有显着增强的环境稳定性。通过在表面硅烷化聚合物上高通量光刻和喷墨印刷高度稳定、可溶液加工和可光聚合的 PQD 获得高分辨率、多色荧光图案,由于牢固的共价键合,可以自由拉伸和折叠而不会分层有机-无机界面。作为概念验证说明,通过光聚合 PQD 与 4D 打印形状变形液晶弹性体的共价结合,展示了光驱动的可自部署信息显示器。这项研究将拓宽具有前所未有功能的钙钛矿聚合物材料在不同领域的新兴应用。
