Literature Seminar Abstract

Mixed-lanthanide metal-organic frameworks (M’LnMOFs) have received wide attention for their use as highly sensitive ratiometric luminescent thermometers. Their high resolutions and non-invasiveness have made them strong candidates for applications such as intracellular sensing and thermal mapping. Unfortunately, materials and techniques for sensing in the physiological temperature range (298-318 K) or higher are still rare. Cadiau et, al. were able to design and synthesize the first ratiometric thermometer in the physiological temperature range. However, higher sensitivity and more accurate sensing in this temperature region are of urgent interest. In this study, a more sensitive and accurate M’LnMOF was synthesized by incorporating a new ligand and different ratios of lanthanide ions. The emission intensity data as a function of temperature showed that a more sensitive and accurate thermometer was created. In their report, a guide has been provided for designing M’LnMOFs thermometers with fast response times and high sensitivities in the physiological temperature region.
