Abstract: A rhodamine-based compound, 2-(2-((3-(tert-butyl)-2-hydroxybenzylidene)amino)ethyl)-3′-6′-bis(ethylamino)-2′,7′-dimethylspiro[indoline-1,9′-xanthen]-3-one, (HL-t-Bu), is reported here as a dual chemosensor for Zn2+ and Al3+ ions. This compound has been synthesized under mild conditions with high yield and characterized by elemental analysis and different… read more here.
