Sumario: | [Image: see text] The main purpose of this study is the synthesis of novel fluorescent Bis-TPE and the investigation of its wide range of photochemical behaviors. For this purpose, initially, Bis-TPE was synthesized. Following this, the interactions of Bis-TPE with a wide range of ions were studied in EtOH using ultraviolet–visible (UV–vis) and fluorescence spectroscopy. As a result of all UV–vis and fluorescence studies, it was determined that Bis-TPE showed turn-on sensor features against Zn(2+) ions. Moreover, the limit of detection (LOD) and K(a) values of Bis-TPE/Zn(2+) were calculated as 0.97 μM (970 nM) and 3.76 × 10(5) M(–1), respectively. Moreover, all reversal studies resulted in switchable on/off variation of the alternative addition of ZnCl(2) and [Bu(4)N]OH to Bis-TPE. This result also implies that the probe Bis-TPE also exhibits specific OH(–) sensor properties in the presence of zinc. |
