Abstract

Lanthanide metal-organic frameworks (Ln-MOFs) exhibit distinctive emission spectra and prolonged luminescent lifetimes, thereby offering a unique platform for the advancement of solid-state photoluminescence (PL) materials. However, the mismatch between the energy levels of metal ions and organic ligands leads to a weak PL emission. Herein, this study presents a pressure-treated strategy aimed at achieving efficient green PL in Tb₂(BDC)₃(H₂O)₄ MOF. Compared to the initial intensity, the PL intensity is enhanced eightfold below 3.1 GPa. Intriguingly, the PL intensity of pressure-treated sample is amplified by 2.5-fold compared to the initial state, and the green emission monochromaticity is maintained. Experiments and calculations reveal that the enhanced hydrogen bonds are retained to the ambient conditions after pressure treatment. They lock the conjugated configuration formed between the planes of carboxyl group and benzene ring, facilitating the intersystem crossing. The reduced distances between metal ions and organic ligands drive the ligand-to-metal energy transfer process. This finding provided significant insights into structure-property relationship of Tb₂(BDC)₃(H₂O)₄, offering a new platform for boosting emission enhancement in Ln-MOFs.

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
