Tailoring the triplet level of isomorphic Eu/Tb mixed MOFs for sensitive temperature sensing

Tailoring the triplet level of isomorphic Eu/Tb mixed MOFs for sensitive temperature sensing

Three different thermo-responsive fluorescent thermometers were constructed by regulating the triplet energy level of organic ligands in isostructural Eu/Tb mixed MOFs. Among them, a quite unusual and rarely reported temperature-dependent fluorescence behavior was observed in LnBDC-NH 2 , and Eu 0.0...

Zusammenfassung:Three different thermo-responsive fluorescent thermometers were constructed by regulating the triplet energy level of organic ligands in isostructural Eu/Tb mixed MOFs. Among them, a quite unusual and rarely reported temperature-dependent fluorescence behavior was observed in LnBDC-NH 2 , and Eu 0.01 Tb 0.99 NDC is effective in the physiological range with the maximum relative sensitivity of 7.32% °C −1 . Different thermo-responsive fluorescence thermometers were obtained by regulating the triplet energy level of organic ligands within isostructural Eu/Tb mixed MOFs.
