摘要: Abstract A new rhodamine-based dual sensor selectively detects Cu 2+ and Fe 3+ . Complexation with triggers the formation of a highly fluorescent ring-open form, while forms nonfluorescent complex detectable by its UV–vis spectrum. Both give an immediate color change sensing mechanism is reversible, as indicated disappearance addition excess EDTA.
