Abstract

original image

You′re my hydroxamate: A chemosensor based on rhodamine hydroxamate with cyclen-tri (tert-butyl ester) and pyridine moiety binding units binds selectively with Pd2+ to induce a strong fluorescence enhancement and color change in aqueous solution. This probe system discriminates Pd2+ over Pt2+ fluorescently and colorimetrically.
