Abstrakt: A novel rhodamine-pyrazole based molecular probe was designed and easily synthesized. The probe could to detect several analytes in aqueous solution at biological pH (HEPES, pH = 7.2). Several heavy metal cations, including Cu 2+ , Fe 3+ , Al 3+ , Hg 2+ and Ni 2+ were detected discriminately by the probe. Also, the novel compound exhibited a good sensory selectivity towards S 2 O 5 2- by both absorption and emission spectra. Moreover, probe/Cu 2+ complex could to detect several anions, including F - , CN - , S 2- , CH 3 COO - , CO 3 2- and NO 2 - . Furthermore, the probe exhibited a high potential to work as a molecular system able to perform a number of logical operations such as AND, NAND, NOR and INHIBIT logic gates.
