The gold element has been used in many different areas throughout history. This includes the treatment of various diseases with drugs containing gold. In contrast to gold metal, gold ions are known to be extremely harmful to the human body. Therefore, the determination of the gold ions in the human body is very important. Gold ion determination can be made by using expensive spectroscopic methods. In contrast to highly expensive spectroscopic methods, chemosensors with high sensitivity and selectivity are a good option to make the gold determination. The bodipy fluorophore is a good example for the metal ion chemosensor. In this study, a bodipybased fluorescence sensor derived from a unique motif that has a triple bond was designed and synthesized. By activating the triple bond of the gold ions, it becomes selective to the gold ions as a result of ırreversible intramolecular cycling.
