New colorimetric chemosensor based on rhodamine hydrazide to detect Cu2+ ions by naked eye

New colorimetric chemosensor based on rhodamine hydrazide to detect Cu2+ ions by naked eye A rhodamine-based chemosensor for naked-eye detection of Cu2+ has been designed and synthesized, which exhibited excellent selectivity and high sensitivity for Cu2+ in CH3CN and CH3CN/H2O mixed solutions. When Cu2+ was added to the solution of sensor 1, a dramatic color change from colorless to bluish violet was observed, while the cations K+, Ca2+, Na+, Hg2+, Zn2+, Co2+, Ni2+, Fe3+, Al3+, Pb2+, Ag+, and Cd2+ did not interfere with the recognition process for Cu2+. The pH effect investigations indicated that it can be applied to analysis of samples over a wide pH range. Research on Chemical Intermediates Springer Journals
