A novel blue-emitting 1,8-naphthalimide fluorophore designed as a molecular PET-based probe for determination of pH and detection of transition metal ions in the environment was successfully synthesized. Novel compound was configured on the "fluorophore-spacer-receptor" format. Due to the tertiary amine receptor the novel system showed "off-on" switching properties under the transition from alkaline to acid media (FE = 3.2) and in the presence of Zn(2+) ions (FE = 2.5). The results obtained illustrate the high potential of the synthesized blue-emitting 1,8-naphthalimide fluorophore as an efficient pH chemosensing material and a selective probe for Zn(2+) ions.
成功合成了一种新型的蓝色发光1,8 - 萘二甲酰亚胺荧光团，该荧光团被设计为一种基于分子正电子发射断层扫描（PET）的探针，用于测定pH值并检测环境中的过渡金属离子。新型化合物采用“荧光团 - 间隔基 - 受体”结构形式。由于叔胺受体，该新型体系在从碱性介质转变为酸性介质时（荧光增强因子FE = 3.2）以及在存在Zn(2+)离子时（荧光增强因子FE = 2.5）表现出“关 - 开”切换特性。所获得的结果表明，合成的蓝色发光1,8 - 萘二甲酰亚胺荧光团作为一种高效的pH化学传感材料和Zn(2+)离子的选择性探针具有很高的潜力。
