Abstract: graph 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 K-d 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.
