| Abstract: | A bis-rhodamine based fluorescent chemosensor for naked-eye detection of Cu2+ with enhanced sensitivity as compared to mono-rhodamine derivative has been synthesized, and its selectivity for Cu2+ in the presence of other competitive metal ions (Li+, Na+, K+, Cs+, Mg2+, Ca2+, Sr2+, Cr3+, Mn2+, Fe2+, Fe3+, Co2+, Ni2+, Zn2+, Cd2+, Hg2+, and Pb2+), and application in bio-imaging are demonstrated. |
