N2 - A thiophene-based chemosensor TP, ((Z)-N′-(pyridine-2-ylmethylene)thiophene-2-carbohydrazide), was synthesized and characterized. TP showed a significant fluorescence enhancement only in the presence of In3+. Importantly, the detection limit was calculated to be 0.61 μM, which is the lowest one reported to date. Job plot and ESI-mass analyses indicated that two TP molecules bind to one In3+ ion. In addition, the sensing mechanism of TP towards In3+ was proposed as chelation-enhanced fluorescence (CHEF) effect from the theoretical calculations.
