Naphthothiophene derivatives are widely used in organic electronics, and in this work, we investigate their potential as part of a “turn-on” sensor system based on rhodamine-naphthothiophene (RNT and RNDT) scaffolds. The photophysical properties of the sensors were studied using ultraviolet-visible...
