Temperature and humidity sensors based on luminescent metal-organic frameworks

Temperature and humidity as important measured physical parameters act an important part in various industrial process controls and human activities, so the accurate detection of them is very important. Sensing materials which generate a signal for detection play a vital role in the sensing identification of temperature and humidity. Among various sensing materials, metal-organic frameworks (MOFs) which consist of metal cations and organic ligands by self-assembly process have great advantages in constructing temperature and humidity sensors with high sensing sensitivity and selectivity due to their good features such as high surface area, structural diversity and tunable luminescent properties. This review intends to provide an update on recent progress in luminescent MOFs for temperature and humidity sensing. It respectively summarizes the signal transduction manners of MOFs in sensing and detection of temperature and water vapour. Examples of the use of luminescent MOFs in the detection of temperature and water vapour are accordingly detailed by different classification. (C) 2020 Elsevier Ltd. All rights reserved.
