An Imidazole-Functionalized Polyfluorene Derivative as Sensitive Fluorescent Probe for Metal Ions and Cyanide
Abstract
To develop sensitive and selective CN − chemosensors, a new imidazole-functionalized polyfluorene ( P1 ) was designed and obtained conveniently, the fluorescence of which could be completely quenched by Cu 2+ ions at the concentration as low as 0.20 ppm in diluted solutions. By utilizing the much higher stability constant of the complex of CN − and Cu 2+, the quenched fluorescence of the solution of P1 by Cu 2+ ions could recover upon the addition of trace CN − anions, with the detection limit down to 0.31 ppm, making P1 a novel, sensitive and selective cyanide probe.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
