protection. In this article, a new multifunction luminescent organic/inorganic hybrid material, named as [ZnL2]·2H2O}n (1) (HL= 3-(pyrid-4-yl)-5-(4-carbonylphenyl)-1,2,4-triazolyl), has been synthesized by hydrothermal method. The investigation indicates that complex 1 can be employed as high selectively fluorescence sensor for selective sensing of ethanol, Fe3+ and pH in solution. The selective sensing

金属离子和有机溶剂分子的选择性检测对环境保护具有重要意义。本文提出了一种新型多功能发光有机/无机杂化材料,命名为[ZnL 2 ]·2H 2 O} n ( 1 ) (HL= 3-(pyrid-4-yl)-5-(4-carbonylphenyl) -
1,2,4-三唑基),采用
水热法合成。研究表明,配合物1可用作高选择性荧光传感器,用于选择性检测溶液中的
乙醇、Fe 3+和pH。Fe 3+的选择性传感是通过猝灭行为实现的,
乙醇分子的荧光变化取决于30 min内的发光增强过程,而1的荧光峰在酸性溶液中也会随着pH值的不同而发生偏移。本文还讨论了1的猝灭效应和传感特性。
