Controllable synthesis of high‐performance materials with low‐cost is critical for the development of functional devices. Herein, a series of sequence‐controlled low‐dispersity oligomers with acid–base chromotropic capability via simple copolymerization between N‐substituted maleimides (NMI) and methyldiallylamine (MDAA) are synthesized. The structure and molecular weight of the oligomers are characterized. Owing to the presence of strong electrophilic carbonyl oxygen and imine nitrogen, a rapid‐responsive color switching system is achieved. This change is attributed to the acid/base‐triggered isomerization between enolate state and the enol or keto tautomer via intramolecular proton transfer. More importantly, the color of P(MDAA/NMI) is regulated by the variation of the substituent group of the N‐substituted maleimide. A new type of rewritable paper based on the designed N‐substituted maleimide oligomers is fabricated by a simple spin‐coating process, on which images with high resolution can be acid‐printed and base‐erased for over ten cycles. The writing and erasure times can be as short as 10 s and the legible time can be more than 90 days under ambient conditions. The as‐formed rewritable paper with excellent rewriting performances is low‐cost and easy for large‐scale production and may find more advanced potential applications in memory devices, rewritable labels, an sensors.

基于低成本N取代的马来酰亚胺低聚物的可持久保存信息的可持久存储介质

以低成本可控地合成高性能材料对于功能设备的开发至关重要。在此，通过N-取代的马来酰亚胺（NMI）和甲基二烯丙基胺（MDAA）之间的简单共聚，合成了一系列具有酸碱发色能力的序列控制的低分散性低聚物。表征了低聚物的结构和分子量。由于存在强亲电的羰基氧和亚胺氮，因此可以实现快速响应的颜色切换系统。这种变化归因于烯醇状态与烯醇或酮互变异构体之间通过分子内质子转移引起的酸/碱引发的异构化。更重要的是，P（MDAA / NMI）的颜色由N-取代的马来酰亚胺的取代基的变化来调节。通过简单的旋涂工艺可以制造出一种基于设计的N-取代的马来酰亚胺低聚物的新型可擦写纸，可以对高分辨力的图像进行酸印刷并对其进行10个周期的碱擦除。在环境条件下，写入和擦除时间可以短至10 s，清晰的时间可以超过90天。形成的具有优异重写性能的可擦写纸成本低廉，易于大规模生产，并可能在存储设备，可擦写标签和传感器中找到更先进的潜在应用。在环境条件下，写入和擦除时间可以短至10 s，清晰的时间可以超过90天。形成的具有优异重写性能的可擦写纸成本低廉，易于大规模生产，并可能在存储设备，可擦写标签和传感器中找到更先进的潜在应用。在环境条件下，写入和擦除时间可以短至10 s，清晰的时间可以超过90天。形成的具有优异重写性能的可擦写纸成本低廉，易于大规模生产，并且可能在存储设备，可擦写标签和传感器中找到更先进的潜在应用。
