金属有机骨架（mof）是一类较新的晶体纳米多孔材料，由于其独特的结构可调性和物理化学性质而备受关注，并在气体储存、气体分离和催化方面取得了成功的应用。mof令人着迷的特性，特别是广泛可调的孔隙度和化学选择性，也使它们成为化学感觉材料的优秀候选类。此外，基于mof的传感器在过去十年中引起了相当大的关注。最近的文献综述主要集中在基于MOF的电子传感器和发光MOF传感器的进展上，而利用MOF的介电特性（折射率）的传感器也得到了最近的展示和讨论。本报告的目的是首次对基于微型光纤的MOF传感器进行综述，并展示MOF作为高灵敏度化学传感介质涂层的潜力。of -MOF传感器的基本原理依赖于MOF折射率的可调性，而折射率的可调性取决于MOF孔中吸附客体分子的数量和类型。综述了基于不同光学传感原理的MOF传感器；最后讨论了of - mof传感器领域面临的挑战和进一步研究的前景。
Metal-organic frameworks (MOFs), a newer class of crystalline nanoporous materials, have been in the limelight owing to their exceptional tunability for structures and physicochemical properties, and have found successful applications in gas storage, gas separation, and catalysis. The mesmerizing properties of MOFs, especially the extensive and tunable porosity and chemical selectivity, also make them an excellent candidate class as chemo-sensory materials. Moreover, MOF-based sensors have attracted considerable attention in the past decade. Recent literature reviews focused on the progress of MOF-based electronic sensors and luminescent MOF sensors, while sensors exploiting the dielectric properties (refractive index) of MOFs were also demonstrated and discussed very recently. The motivation of this report is to provide, for the first time, a general review on such MOF sensors with a particular focus on miniature optical fiber (OF) based MOF sensors and to demonstrate the promising potential of MOFs as dielectric coatings on OF for highly sensitive chemical sensing. The fundamental principle of OF-MOF sensors relies on the tunability of the refractive index of a MOF, which is dependent on the amount and type of adsorbed guest molecules in the MOF pores. MOF sensors based on different optical sensing principles are reviewed; challenges and perspectives on further research into the field of OF-MOF sensors are also discussed.
