抄録	Seven-coordinate Tb-III complexes with strong luminescence and thermosensing properties are reported. Mononuclear [Tb(tmh)(3)(PEB)] [tmh: 2,2,6,6-tetramethyl-3,5-heptanedione, PEB: (diphenylphosphoryl)ethynyl]benzene and dinuclear [Tb-2(tmh)(6)(m-BPEB)] [m-BPEB: 1,3-bis(diphenylphosphoryl)ethynyl]benzene were characterized by single-crystal X-ray analysis. The quantum yields of [Tb(tmh)(3)(PEB)] and [Tb-2(tmh)(6)(m-BPEB)] were estimated to be 71 and 39%, respectively. Thermosensing properties are evaluated by temperature-dependent emission lifetime measurements (Arrhenius analysis), which are affected by the presence of ligand-to-ligand charge transfer (LLCT) bands. The LLCT bands are confirmed by DFT calculations.
