通过液相各向异性外延生长获得了核壳或条纹杂原子镧系金属-有机骨架分层单晶，在保持相同的周期组织的同时表现出空间分离的结构。提出了不同类型的区域和方向控制的多色光物理模型，这些模型要么显示视觉可分辨的，要么显示可见/近红外（NIR）发射色。这为分层分子系统的设计提供了一种新的自下而上的策略，提供了高通量和多路发光颜色可调性和可读性。建立了光谱编码与三维（三维）微尺度空间编码相结合的独特能力，在防伪、彩色条形码等集成化、小型化光电材料和器件方面具有潜在的应用前景。
Core-shell or striped heteroatomic lanthanide metal-organic framework hierarchical single crystals were obtained by liquid-phase anisotropic epitaxial growth, maintaining identical periodic organization while simultaneously exhibiting spatially segregated structure. Different types of domain and orientation-controlled multicolor photophysical models are presented, which show either visually distinguishable or visible/near infrared (NIR) emissive colors. This provides a new bottom-up strategy toward the design of hierarchical molecular systems, offering high-throughput and multiplexed luminescence color tunability and readability. The unique capability of combining spectroscopic coding with 3D (three-dimensional) microscale spatial coding is established, providing potential applications in anti-counterfeiting, color barcoding, and other types of integrated and miniaturized optoelectronic materials and devices.
