Abstract
Rhodamine dyes have been attracted to many researchers due to its excellent photophysical properties. Interesting one of these dyes is rhodamine 6G. In this study, we have designed and synthesized a strong yellowish-green fluorescent emission dye sensor based rhodamine 6G for the detection of Hg2+ ions. It has noticeable properties of application for detecting and recognizing the presence of Hg2+ ions. In this regard, the optical properties of this dye sensor were intensively investigated using UV-Vis absorption, fluorescent spectrophotometer. Formation type of metal binding complex for this dye sensor was also determined by Job's plot method. Finally, computational calculation was simulated and calculated to approach for HOMO/LUMO of this dye sensor.
