Abstract

Abstract : A ligand with its triplet state located between the excited states of the Tb and Eu ions shows effective facilitation in the energy transfer process between them, and the energy transfer process in this case is also influenced by polar guest solvent molecules. Abstract : Luminescent lanthanide MOF materials are good sensors for analyzing some specific gas or volatile small molecules. However, some potential interference factors coming from the material itself, such as bridging ligands or guest solvent molecules entrapped in the channel of a MOF, were usually ignored during the sensing process. Here, two Tb : Eu-codoped indium-based MOFs with different bridging ligands were obtained for exploring the effects of ligand and guest solvent molecules on their luminescence properties. The current studies demonstrated that a ligand in the triplet state located between the excited states of Tb and Eu and polar guest solvent molecules encapsulated in the lanthanide MOF with such a type of ligand as the linker can interfere with the sensing process since they can substantially facilitate the energy transfer between Tb and Eu.
