开发新的存储介质以满足多样化信息存储场景的需求是一个巨大的挑战。在这里,开发了一系列具有超强机械性能和出色可塑性的镧系发光有机凝胶,用于图案化信息存储和加密应用。通过天然DNA、合成配体和稀土离子之间的静电作用和配位作用,制备了具有优异力学性能和可调发光颜色的有机凝胶。有机凝胶-RE可以拉伸180倍,并显示出80 MPa的超强断裂强度。有机凝胶RE成功地展示了一系列具有信息存储和加密功能的应用,例如自信息模式,快速响应(QR)码和条形码。所开发的信息存储系统具有良好的可加工性、高拉伸性、优异的稳定性和信息图案的通用设计的各种优点。因此,有机凝胶稀土基信息存储系统适用于不同场景下的应用,例如重复粗暴操作的柔性设备。这些进展将使发光有机凝胶-RE的设计和开发成为各种场景的信息存储和加密介质。采用超分子络合法制备了高增塑、超强力学性能的镧系有机凝胶。图案化的信息存储和加密应用是通过有机凝胶的柔性发光以通用的方式实现的。这项工作提供了新的存储介质,以满足不同的信息存储场景的需求。
The development of new storage media to meet the demands for diverse information storage scenarios is a great challenge. Here, a series of lanthanide‐based luminescent organogels with ultrastrong mechanical performance and outstanding plasticity are developed for patterned information storage and encryption applications. The organogels possessing outstanding mechanical properties and tunable luminescent colors are prepared by electrostatic and coordinative interactions between natural DNA, synthetic ligands, and rare earth (RE) ions. The organogel‐REs can be stretched by 180 times and show an ultrastrong breaking strength of 80 MPa. A series of applications with both information storage and encryption, such as self‐information pattern, quick response (QR) code, and barcode, are successfully demonstrated by the organogel‐REs. The developed information storage systems have various advantages of good processability, high stretchability, excellent stability, and versatile design of information patterns. Therefore, the organogel‐RE‐based information storage systems are suitable for applications under different scenarios, such as flexible devices under repeating rude operations. The advancements will enable the design and development of luminescent organogel‐REs as information storage and encryption media for various scenarios. Highly plasticized and mechanically ultrastrong lanthanide organogels are fabricated by supramolecular complexation. Patterned information storage and encryption applications are realized in a versatile way by the flexible luminescence of organogels. This work offers new storage media to meet the demands for diverse information storage scenarios.
