Fluorescent probes 1 and 2 were conveniently synthesized from 4-sulfo-1, 8-naphthalic anhydride, potassium salt, and 4 0 -aminobenzo-15-crown-5 and also from 4 0 -aminobenzo-18-crown-6. These sensors exhibit dual emission and ratiometric absorption, are water soluble, and show good selectivity for s
## Abstract A new non‐ionic water‐soluble polyfluorene that contains two benzo‐18‐crown‐6 side chains per repeat unit (PFDC) is synthesized and characterized. Upon addition of Pb^2+^ ions to a solution of PFDC, the PFDC fluorescence is strongly quenched. The minor interference from other metal ions
