| Abstract: | Temperature-dependent luminescence of a dinuclear Eu-III/Tb-III complex with a seven-coordinate structure is demonstrated. The dinuclear complex is composed of two lanthanide ions, six tetramethylheptanedionate ligands, and a bidentate phosphine oxide linker ligand. The dinuclear structure of the complex was characterized by single-crystal XRD. Intrinsic 4f-4f emission quantum yields of the dinuclear Eu-III and Tb-III complexes were 66 and 61%, respectively. The luminescence color of the dinuclear Eu-III/Tb-III complex changed from red to green with increasing temperature. The thermosensing range based on the ratio of luminescence intensity (A(Eu)/A(Tb)) was 100-450K. The temperature-dependent luminescence is due to the presence of a ligand-to-metal charge-transfer state. |
