Complexing Eu(3+)/Tb(3+) in a Nanoscale Postmodified Zr-MOF toward Temperature-Modulated Multispectrum Chromism.
Karmakar S, Ghosh A, Rahimi FA, Rawat B, Maji TK. Karmakar S, et al. ACS Appl Mater Interfaces. 2022 Nov 2;14(43):49014-49025. doi: 10.1021/acsami.2c15079. Epub 2022 Oct 24. ACS Appl Mater Interfaces. 2022. PMID: 36278376
To achieve this goal, we have devised a unique design and facile multistep synthesis of Zr-ctpy-NMOF@Tb(x)Eu(y) compounds by confining Ln-complexes (Ln = Eu(3+)/Tb(3+)) into a robust nanoscale Zr-NMOF (MOF-808) via postsynthetic modification. Covalent graftin …
