Abstract:
A fluorine-modified tetracarboxylic acid ligand, namely, 2'-fluoro-[1,1':4',1''-terphenyl]-3,3'',5,5''-tetracarboxylic acid (H4FTPTC), with suitable triplet energy excited state, was designed and applied to construct the luminescent lanthanide metal-organic frameworks (LnMOFs) for cryogenic temperature sensing. With the lanthanides codoping strategy, we developed a new Tb3+/Eu3+ mixed LnMOF system Tb1- xEu xFTPTC ( x = 0.05, 0.1, 0.2), which feature excellent linear responses to temperature with high relative sensitivity in the cryogenic range of 25-125 K. It was found that the relative sensitivity of such mixed LnMOF could readily be tuned by adjusting the incorporation amount of Eu3+ ions in the host framework. In addition, the energy transfer efficiency between the Tb3+ and Eu3+ ions in the framework with different Tb3+/Eu3+ ratios are also investigated and discussed.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
