Popis:	A rhodamine-based sensor ( 1 ) has been developed for the detection of chromium ions. Cr 3+ -induced opening of the rhodamine spirocycle in sensor ( 1 ) led to the distinct colorimetric and fluorescence responses. Among all the tested ions, only Cr 3+ generated a significant fluorescence enhancement of up to 13-fold, which indicated the high selectivity of 1 . Sensor ( 1 ) was successfully applied in the in vivo fluorescence imaging of Cr 3+ in C. elegans . The results provided solid evidences for the future estimation of Cr 3+ in environmental applications and tobacco samples.
