Rewritable paper has recently become prevalent in both academic research and marketplace due to the potential environmental advantages, including forest conservation, pollution reduction, energy saving and resource sustainability. However, its real-life applications are limited by a lack of effective strategy to realize multicolour and water-jet printing on rewritable paper with long legible image-lasting times. Herein, we report an effective strategy to construct rewritable paper based on colour or luminescence switching induced by dynamic metal-ligand coordination. This type of rewritable paper can be conveniently utilized for multicolour water-jet printing by using aqueous solutions containing different metal salts as ink. In addition, the printed images on the water-jet rewritable paper can be retained for a long time (> 6 months), which shows great progress compared to previous work. We believe that this type of rewritable paper could be considered as a prototype for multicolour water-jet printing to meet the practical needs.
由于具有潜在的环境优势，包括森林保护、减少污染、节能和资源可持续性，可重写纸最近在学术研究和市场中都变得很普遍。然而，其实际应用受到限制，因为缺乏一种有效的策略来在可重写纸上实现多色和水喷射印刷，且图像的可读保留时间长。在此，我们报告了一种基于动态金属-配体配位诱导的颜色或发光切换来构建可重写纸的有效策略。这种类型的可重写纸可以通过使用含有不同金属盐的水溶液作为墨水方便地用于多色水喷射印刷。此外，水喷射可重写纸上的印刷图像可以长时间保留（>6个月），与之前的工作相比有了很大的进步。我们相信，这种类型的可重写纸可以被视为满足实际需求的多色水喷射印刷的原型。
