چکیده

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.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
