这项工作为快速生成具有广泛长度的上部结构组件提供了平台，这些组件可用于访问各种基于金属-有机络合物的软上部结构。在二氯甲烷和乙酸乙酯中制备了直径为纳米、长度为毫米的金属基微针，其尺寸可以通过调节两种溶剂的比例来控制。有趣的是，在溶剂挥发过程中，微针可以通过进一步组装形成微花结构。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戊二烯的共同组装来扩大发射从蓝色和绿色到红色的超结构的范围。类似于赖氨酸修饰的茂金属与微花的共同组装，在组装过程中，叶绿素-a和维生素B12被引入到微花中，这可能在未来的能量捕获和神经修复的研究中被利用。
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 B12 were introduced into the microflowers during the assembly process, which may be exploited in studies of energy capture and nerve repair in the future.
