1,4‐ and 1,5‐Disubstituted 1,2,3‐triazole scaffolds as surrogate of amide with large dipole moment have been utilized to access two isomeric naphthylthiourea‐based chemosensors 1 and 2 in appreciable overall yields. The easily synthesizable chemosensors 1 and 2 are designed to recognize anions and also to realize a comparative view on their sensing potentials. Different inorganic phosphates and a group of phosphorylated nucleosides such as ATP, ADP and AMP are selectively recognized by these chemosensors in semi aqueous system. The fluorometric study revealed that both the sensors sensed ATP selectively in CH 3 CN/H 2 O (4/1,v/v) by showing considerable increase in emission. 1,4‐Disubstituted triazole‐based sensor 1 has been established to be more effective than the 1,5‐disubstituted triazole‐based sensor 2 in selective sensing of ATP.
