Highly effective discrimination of catecholamine derivatives via FRET-on/off processes induced by the intermolecular assembly with two fluorescence sensors.

We proudly presented the novel sensor system based on intermolecular assembled complexes of two fluorescence sensors and a suitable catecholamine acting as a guest linker by the reaction between boronic acid and aldehyde moieties of the sensors with the diol and amine units of catecholamines, respectively. The FRET-on/off induced by the assembly could discriminate structural similarity of catecholamines.
