摘要：

Two pyramid-like lanthanide titanium oxo clusters formulated as LnTi(9)(mu(2)-O)(5)(mu(3)-O)(7)(mu(3)-OH)(2)(OiPr) (acac)(2)(TCA)(10)(THF) (LnTi(9), Ln = Eu / Tb, HTCA = 2-thiophenecarboxylic acid) were prepared through the reaction of Ln(acac)(3), 2-thiophenecarboxylic acid (HTCA), Ti(OiPr) (4) and THF. The 10-nuclearity-metal-core [LnTi(9)(mu(2)-O)(5)(mu(3)-O)(7)(mu(3)-OH)(2)](13+) is protected by four kinds of ligands. EuTi9 and TbTi9 exhibit characteristic emissions of Eu3+ / Tb3+ under ultraviolet excitation. The temperature-dependent luminescence results show EuTi9 shows a good linear relationship between the luminescence intensity and temperature range of 80-320 K, while TbTi9 has high temperature-sensitivity in different temperature ranges.
