    A highly selective rhodamine based color turn on and fluorescence turn off sensor toward late IB metal ions

    A fluorescence “turn-off” and color “turn-on” probe for late IB metal ions (Fe3+/Co2+/Ni2+/Cu2+/Zn2+) was developed based on rhodamine B. The probe was synthesized by condensation between rhodamine B and 8-hydrox...
