Abstract

The main purpose of this study is the synthesis of novelfluorescent Bis-TPE and the investigation of its widerange of photochemicalbehaviors. For this purpose, initially, Bis-TPE was synthesized.Following this, the interactions of Bis-TPE with a widerange of ions were studied in EtOH using ultraviolet-visible(UV-vis) and fluorescence spectroscopy. As a result of allUV-vis and fluorescence studies, it was determined that Bis-TPE showed turn-on sensor features against Zn2+ ions. Moreover, the limit of detection (LOD) and K (a) values of Bis-TPE/Zn2+ were calculated as0.97 & mu;M (970 nM) and 3.76 x 10(5) M-1, respectively. Moreover, all reversal studies resulted in switchableon/off variation of the alternative addition of ZnCl2 and[Bu4N]OH to Bis-TPE. This result also impliesthat the probe Bis-TPE also exhibits specific OH- sensor properties in the presence of zinc.
