Design and Ultrasound-Assisted Synthesis of an anthracene-based Cu-MOFfor Hydrogen Sulfide Sensing

Copper metal-organic framework (Cu-MOF) fluorescent sensing is a relatively new areaof research in the field of materials science and chemical sensing. Cu-MOFs are porous materialsthat have been found to exhibit unique fluorescence properties, which make them attractive for usein sensing applications. H۲S is a toxic gas that is commonly found in natural gas, crude oil, andother industrial processes. It poses a serious threat to human health and safety, and therefore, thereis a need for reliable and sensitive detection methods. Cu-MOFs sensors have been shown highsensitivity and selectivity towards H۲S gas, making them a promising candidate for H۲S sensingapplications. In addition, anthracene is a common ligand that has been used as a linker in thesynthesis of Cu-MOFs for fluorescent sensing applications[۱,۲]. In this study, a novel anthracenebasedCu-MOF has been synthesized under ultrasound irradiation and used for H۲S detection. TheCu-MOF as a fluorescent sensor has surprising performance and has shown great promise inenvironmental and industrial monitoring. The ultrasonic-assisted synthesis method was found toproduce smaller and more uniform crystals compared to traditional synthesis methods.Interestingly, fluorescence detection studies exhibit that Cu-MOF can detect hydrogen sulfide withhigh sensitivity and selectivity in the presence of interfering species and also show a quickresponse in a short time range in water.
