This work provides a platform for the rapid generation of superstructure assemblies with a wide range of lengths that can be used to access a variety of metal-organic complex-based soft superstructures. Metallacage-based microneedles that are nanometers in diameter and millimeters in length were generated in dichloromethane and ethyl acetate; their size could be controlled by adjusting the ratio of the two solvents. Interestingly, microflower structures could be formed by further assembly of the microneedles during solvent evaporation. Our study establishes a feasible method designed to broaden the range of suprastructures with emissions from blue and green to red through the co-assembly of lysine-modified perylene. Similar to the co-assembly of lysine-modified perylene with microflowers, chlorophyll-a and vitamin B were introduced into the microflowers during the assembly process, which may be exploited in studies of energy capture and nerve repair in the future.
这项工作为快速生成具有广泛长度的超结构组件提供了一个平台,可用于访问各种基于金属有机配合物的软超结构。在二氯甲烷和乙酸乙酯中生成了基于金属笼的纳米级直径和毫米级长度的微针; 通过调整两种溶剂的比例可以控制其尺寸。有趣的是,在溶剂蒸发过程中,微针进一步组装可以形成微花结构。我们的研究建立了一种可行的方法,旨在通过赖氨酸修饰的苝的共组装,将发光从蓝色和绿色拓宽到红色。类似于赖氨酸修饰的苝与微花的共组装,在组装过程中,叶绿素-a 和维生素 B 被引入微花中,这在未来的能量捕获和神经修复研究中可能会得到利用。
