Abstract

The precise construction and programmable assembly of structures with specific topologies remain persistent challenges in crystal engineering, primarily constrained by the limited availability of building blocks. Utilizing a synergistic approach that combines an in situ-formed concave polyoxovanadate (POV) cluster {VV₄} with specifically designed 120° ditopic carboxylic acid bridging ligands, we successfully synthesized a series of wine-rack-type supramolecular macrocycles characterized by the general formula [(V₅O₉Cl)₄(L)₈]^8-. The experimental results demonstrate that the introduction of sulfonic acid groups enables controlled structural extension into 1D chain and 2D layer architectures, manifesting the unique advantages of POV-based wine-rack units in constructing framework-based porous materials. This work significantly contributes to the structural diversity of wine-rack-type supramolecular architectures while simultaneously highlighting the great potential of polyoxometalate-driven supramolecular assemblies in materials science.

基于多钒氧酸盐的酒架型超分子大环的合成、结构及染料吸附性能。

具有特定拓扑结构的精确构造和可编程组装仍然是晶体工程中持续存在的挑战，主要受到构建块有限可用性的限制。利用原位形成的凹形聚钒氧酸（POV）簇{VV4}与专门设计的120°双位羧酸桥接配体的协同方法，我们成功合成了一系列酒架型超分子大环，其通式为[(V5O9Cl)4(L)8]8-。实验结果表明，引入磺酸基团可以使结构可控地扩展到一维链和二维层结构，体现了基于pov的酒架单元在构建基于框架的多孔材料方面的独特优势。这项工作极大地促进了酒架型超分子结构的多样性，同时也突出了多金属氧酸盐驱动的超分子组装在材料科学中的巨大潜力。

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
