Copper(II) ionColorimetricFluorescenceGel ballThe development of sensitive colorimetric and fluorescent chemosensors for Cu sensing has gained much attention in recent years because of their potential application in clinical biochemistry and environmental studies. Herein, a novel rhodamine-based chemosensor ...
The effect of substituents on FRET in two newly designed rhodamine-based Hg2+ion selective chemosensors (L1andL2) has been explored by a systematic experimental and theoretical study. Comparison of these sensors in the analytical study and imaging of Hg2+ions in living cells has also been included...
Figure 1.5.Fluorogenic molecules based on rhodamine derivatives. In addition to acylation of the nitrogen substituents, the zwitterionic nature of the rhodamine structure in aqueous solution allows a mode of fluorescence modulation that is unique to the rhodamine and isologous dyes.Amidationof theortho...
The development of highly sensitive and selective fluorescent chemosensors over recent years has attracted great interest1,2,3,4,5,6,7. One such element of interest is aluminium being the third most abundant element worldwide, and being significantly utilised in various applications such as in the...

19 As is known to all, the rhodamine framework is easily modified at a well-defined molecular level for constructing ‘off–on’ fluorescent or colorimetric chemosensors due to its special structural feature.20 Up to now, a number of rhodamine spirolactam-based probes have been designed and ...
Various rhodamine-based optical chemosensors for different cations have been reported [[11], [12], [13], [14], [15], [16], [17]]. Generally, these sensors are rhodamine dyes modified with chelation groups for selective binding of target cations. Sensing mechanism is based on the ...
