Abstract
Official abstract text for this publication.
Two rhodamine reversible fluorescent sensor derivatives, L 1 and L 2 , bearing 2-methoxy-1-naphthaldehyde and 5-bromo-3-methoxy salicylaldehyde units were synthesized using microwave-assisted organic synthesis and used for selective and sensitive reversible sequential fluorescence detection of aluminum ion (Al 3+ ) and azide (N 3− ) in aqueous acetonitrile solution via the fluorescence spectral changes. Stoichiometry and binding mechanisms for both sensors are well characterized and established by the respective spectroscopic techniques. L 1 and L 2 sensors are useful for the analysis of Al 3+ and N 3− in environmental samples and biological studies.
