Description
Summary:The ongoing need for accurate measurement of temperature in microelectronic diagnosis is driving the development of novel temperature sensors. In this work, we synthesized a tetracarboxylic acid ligand containing a pyridine moiety to construct a three-dimensional lanthanide MOF EuPDDI (H 4 PDDI = 5,5′-(pyridine-2,5-diyl)diisophthalic acid). Thermal analysis shows the favourable thermal stability of the main framework of EuPDDI up to 380 °C. By Eu 3+ and Tb 3+ co-doping, a mixed LnMOF thermometer Eu 0.19 Tb 0.81 PDDI , effective in the temperature range of 313 to 473 K, was obtained. Its features include high relative sensitivity, and accurate temperature resolution. Such a LnMOF is useful for temperature sensing and diagnosis in microelectronics.
