配位化学和超分子化学之间存在协同作用,这导致了具有多种功能的创新分层复合材料的开发。这里,我们提出了一种在富勒烯(MOFOF)复合材料上合成和表征金属有机骨架的新方法,通过配位化学和超分子化学原理的整合实现。MOFOF的分层性质利用了金属有机骨架和富勒烯的固有性质。两步合成程序涉及将富勒烯受控组装为管状纳米结构(富勒烯纳米管:FNT),它们的表面功能化,以及MOF的表面生长(在这种情况下,ZIF-67).该方法允许精确调整形态,MOF-on-FNT的有效分布,和严格的成分控制。使用电子显微镜对材料进行了全面的结构表征,光谱技术,和其他方法来阐明MOFOF复合材料内的独特特征和相互作用。主要发现表明,MOFOF复合材料的新型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性能的高级分层复合材料。包括微孔和中孔通道,界面面,和缺陷部位。这些特性预计将导致许多潜在的应用,如气体储存和分离,催化作用,传感,储能,和环境修复。然而,只有酸蒸汽传感的能力进行了测试和描述在这里。
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.
