Metal ion induced FRET OFF-ON in tren/dansyl-appended rhodamine.
A series of new fluorescent probes bearing tren-spaced rhodamine B and dansyl groups have been synthesized. Compound 1 exhibits selective changes in the absorption and the emission spectra toward Cu2+ ion over miscellaneous metal cations. Among 1-3, 1 shows the best FRET efficiency through dansyl emission to rhodamine absorption for the Cu2+ ion.
