Integration of devices based on metal–organic frameworks: A promising platform for chemical sensing

Chemical sensor devices are rapidly developing due to the demand for healthcare, environmental monitoring, manufacturing industry and smart home. Unlike traditional materials, metal–organic frameworks (MOFs) exhibit excellent prospects in chemical sensing devices due to the designability of metals and ligands, tunable pore size and abundant functional sites. By integrating MOFs with devices, the excellent sensing performance of MOFs and the portability of devices have been combined, making them stand out in areas such as gas detection and disease diagnosis. Here, we summarize the basic methods for combining MOFs with devices, the sensing mechanisms and chemical sensor devices based on MOFs in recent years, including electrochemical, electronic, electromechanical and optoelectronic sensor and devices. Finally, inspired by previous studies, the drawbacks and future prospects of chemical sensing devices based on MOFs are presented.
