Abstract

[structure: see text] A potassium-selective fluorescent BODIPY-linked azacrown ether chemosensor has been synthesized using novel substitution reactions of 3,5-dichloroBODIPY. The indicator absorbs and emits light in the visible wavelength range. The dissociation constant Kd for the complex between K+ and the probe is 0.5 mM in acetonitrile. Quantum chemical calculations show that the experimental hypsochromic shifts in absorption and fluorescence upon potassium binding are due to complexation, which induces a large conformational change of the sensor.

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.
