dc.description.abstractHerein we report on the sensor activity of three blue-emitting triazine derivatives of 2-aminoterephthalic acid. The novelfompounds are conigured as a ``luorophore-receptor`` system. The luorophores designed can act as a pH-probe via an ``off-on-off`` luorescence sensing mechanism due to an internal charge transfer. The sensor activity towards cations and anions in water/DMF (1:1, v/v) media is studied by monitoring the luorescence intensity changes. The ions tested exert a high quenching effect suggesting that the compounds are sensitive to strong acid (pH<3) and strong alkaline media (pH>8). The logic function XNOR can be performed using an acid and a base as chemical inputs, while a digital comparator can be designed on the ground of pH induced changes in the spectral properties of the novel molecule.
