ABSTRACT
Three new rhodamine-based probes Y1-Y3 were synthesized as "off-on" chemosensors for Fe(3+) imaging in living cells. The recognizing behaviors investigated both experimentally and computationally. crystal structure of the complex Y3-Fe(3+) revealed that preferred to coordinate with N atom benzothiazole moiety rather than O carboxyl group.
