Precise control of the void environment, achieved through multiple functional groups and enhanced by structural adaptations to guest molecules, stands at the forefront of scientific inquiry. Flexible multivariate open framework materials (OFMs), including covalent organic frameworks and metal-organic frameworks, meet these criteria and are expected to play a crucial role in gas storage and separation, pollutant removal, and catalysis. Nevertheless, there is a notable lack of critical evaluation of achievements in their chemistry and future prospects for their development or implementation. To provide a comprehensive historical context, the initial discussion explores into the realm of "classical" flexible OFMs, where their origin, various modes of flexibility, similarities to proteins, advanced tuning methods, and recent applications are explored. Subsequently, multivariate flexible materials, the methodologies involved in their synthesis, and horizons of their application are focussed. Furthermore, the reader to the concept of spatial distribution is introduced, providing a brief overview of the latest reports that have contributed to its elucidation. In summary, the critical review not only explores the landscape of multivariate flexible materials but also sheds light on the obstacles that the scientific community must overcome to fully unlock the potential of this fascinating field.
通过多个官能团实现对空隙环境的精确控制，并通过对客体分子的结构适应性加以增强，这处于科学探究的前沿。包括共价有机框架和金属有机框架在内的柔性多元开放框架材料（OFMs）符合这些标准，有望在气体存储与分离、污染物去除及催化方面发挥关键作用。然而，对其化学领域的成就以及未来发展或应用前景缺乏重要评估。为提供全面的历史背景，开篇讨论深入到“经典”柔性OFMs领域，探讨其起源、各种柔性模式、与蛋白质的相似性、先进的调控方法及近期应用。随后，聚焦于多元柔性材料、其合成所涉及的方法及其应用前景。此外，引入了空间分布概念，简要概述了有助于阐明该概念的最新报告。总之，这篇批判性综述不仅探讨了多元柔性材料的概况，还揭示了科学界为充分释放这一迷人领域的潜力必须克服的障碍。
