Pillararene-modified graphene materials integrate the advantages of both graphene and pillararenes; , the cavity of pillararenes can recognise suitably sized electron-deficient and hydrophobic guest molecules host-guest interactions, while the graphene composite is able to exhibit unique physiochemical properties including inertness, nanoscale, electrical and thermal structural properties. Those novel organic-inorganic hybrid composites can be efficiently prepared both covalent and noncovalent bonds by classic organic reactions and supramolecular interactions, respectively. Pillararene-functionalised graphene materials have been used in various applications, such as electrochemical sensing guest molecules, performing as the platform for fluorescent probes, carrying out fluorescence quenching as the sensor, biosensing toxic molecules in cells, Raman and fluorescence bioimaging of cancer cells, photoacoustic and ultrasound imaging, as well as storage materials and reactors in energy fields.
柱芳烃修饰的石墨烯材料兼具石墨烯和柱芳烃的优点；柱芳烃的空腔可以通过主客体相互作用识别尺寸合适的缺电子和疏水客体分子，而石墨烯复合材料能够展现出包括惰性、纳米级、电学和热学结构性质在内的独特物理化学性质。这些新型有机-无机杂化复合材料可以分别通过经典有机反应的共价键和超分子相互作用的非共价键高效制备。柱芳烃功能化的石墨烯材料已被用于各种应用，如电化学传感客体分子、作为荧光探针的平台、作为传感器进行荧光猝灭、生物传感细胞中的有毒分子、癌细胞的拉曼和荧光生物成像、光声和超声成像，以及能源领域的存储材料和反应器。
