lanthanum-based coordination polymer LaHL, ([La(HL)(H2O)2]·H2O}n, H4L = 5-hydroxy-1,2,4-benzenetricarboxylic acid) has been synthesized by hydrothermal methods. By the addition of 5 % of a Tb or Eu salt to the reaction mixture, the doped compounds La0.95Tb0.05HL and La0.95Eu0.05HL were obtained, with the same structure as LaHL. The compound La0.95Tb0.05HL can be used as a ratiometric thermometer over the
采用水热法合成了新型发光镧基配位聚合物LaHL,([La(HL)(H2O)2]·H2O}n, H4L = 5-羟基-1,2,4-苯三甲酸)。通过向反应混合物中加入5%的Tb或Eu盐,得到了与LaHL结构相同的掺杂化合物La0.95Tb0.05HL和La0.95Eu0.05HL。化合物 La0.95Tb0.05HL 可用作比例温度计,温度范围为 90–280 K,在 280 K 时灵敏度高达 0.53 % K–1。
