A novel trichromophoric molecular chemosensor Rh-NI-Hz was designed,synthesized and examined f<detection.It exhibited naked eye observed colorimetric and fluorometric responses to lower and high pH v The probe sensitivity towards an acidic environment was achieved through the rhodamine part of the mo] where the colour was changed from colourless to red and yellow fluorescence was emitted.On the other ha:a basic environment,the colour was changed to yellow and a green fluorescence emission was prod Moreover,the probe mimics a digital comparator by executing three INHIBIT logic gates using H+ and H<chemical inputs.
