There is a synergy between coordination chemistry and supramolecular chemistry that has led to the development of innovative hierarchical composites with diverse functionalities. Here, we present a novel approach for the synthesis and characterization of a metal–organic framework on fullerene (MOFOF) composites, achieved through the integration of coordination chemistry and supramolecular chemistry principles. The hierarchical nature of the MOFOF harnesses the inherent properties of metal–organic frameworks and fullerenes. The two-step synthesis procedure involves controlled assembly of fullerenes as tube-like nanostructures (fullerene nanotube: FNT), their surface functionalization, and the on-surface growth of the MOF (in this case, ZIF-67). The method permits the precise tuning of morphology, effective distribution of MOF-on-FNT, and tight compositional control. The materials were comprehensively structurally characterized using electron microscopy, spectroscopic techniques, and other methods to elucidate the unique features and interactions within the MOFOF composites. The main findings reveal that the novel synthesis and characterization of MOFOF composites demonstrate the successful integration of coordination chemistry and supramolecular chemistry for the designing and fabricating of advanced hierarchical composites with tailored properties, including micro- and mesopore channels, interfacial facets, and defect sites. These properties are expected to lead to numerous potential applications such as gas storage and separation, catalysis, sensing, energy storage, and environmental remediation. However, only the capability of acid vapor sensing was tested and is described here.

配位化学和超分子化学相结合的富勒烯金属有机框架（MOFOF）作为多级复合材料

配位化学和超分子化学之间的协同作用导致了具有多种功能的创新分层复合材料的开发。在这里，我们提出了一种富勒烯金属有机骨架（MOFOF）复合材料的合成和表征的新方法，该方法通过配位化学和超分子化学原理的整合来实现。 MOFOF 的分层性质利用了金属有机框架和富勒烯的固有特性。两步合成过程涉及富勒烯作为管状纳米结构（富勒烯纳米管：FNT）的受控组装、其表面功能化以及 MOF（在本例中为 ZIF-67）的表面生长。该方法可以精确调节形态、MOF-on-FNT 的有效分布以及严格的成分控制。使用电子显微镜、光谱技术和其他方法对材料进行了全面的结构表征，以阐明 MOFOF 复合材料的独特特征和相互作用。主要研究结果表明，MOFOF复合材料的新颖合成和表征证明了配位化学和超分子化学的成功整合，用于设计和制造具有定制特性的先进分层复合材料，包括微孔和中孔通道、界面面和缺陷位点。这些特性预计将带来许多潜在的应用，例如气体存储和分离、催化、传感、能量存储和环境修复。然而，此处仅测试并描述了酸蒸气传感的能力。
