Back Cover: Developing Luminescent Ratiometric Thermometers Based on a Covalent Organic Framework (COF) (Angew. Chem. Int. Ed. 5/2020)
Abstract
Covalent organic frameworks (COFs) can be grafted with Eu3+ and Tb3+ complexes, which decrease the pore size of the material when attached to the COF. As reported by A. M. Kaczmarek, L. D. Carlos et al. in their Research Article on page 1932, the Eu3+ and Tb3+ ions emit red and green light, respectively, and allow the system to be used as a luminescence thermometer. This is the first reported example of a COF material being used for this application.
