A new star host, hexakis (carboxylphenyl-2-thiolmethyl)benzene (1H6), has been synthesized by a simple one-step condensation procedure with the high yield. Crystal structure of the DMSO adduct 1H6.6DMSO (2) reveals it to be rhombohedral crystal system, space group R-3, with a =b=2.4129(2), c= 1.1576(3) nm, α=β= 90°γ = 120°?V=5.837(2) nm3,Z=3. The six arms of side benzole acid rings and the H-bonded DMSO molecules are located alternatively above and below the central benzene plane with “1,3,5-up/2,4,6-down” conformation. Terbium complex (Tb21)2Py.9H2O (3) was prepared in hot pyridine, which shows bright characterized Tb(Ⅲ) emission with a longer lifetime and higher luminescent intensity than that of the corresponding terbium benzoate in solid state. These observations suggest that host 1 is a good antenna for sensitizing TbⅢ emission.
