Abstract

Abstract : A BINOL (1, 1′-bi-2-naphthol)-based probe1 with a diamide group has been synthesized and investigated for its photophysical behavior towards various cations and anions. Abstract : A BINOL (1, 1′-bi-2-naphthol)-based probe1 with a diamide group has been synthesized and investigated for its photophysical behavior towards various cations and anions. Probe1 has been used for the estimation of Al 3+ and Cu 2+ ions in the presence of other metal ions, signaling the binding event through the formation of new absorption bands at 415 and 430 nm. Differential emission bands are formed in the presence of Al 3+ at 515 nm and Zn 2+ at 485 nm, while quenching is observed in case of Cu 2+ ion. Probe1 shows selective estimation for CN − ion among all other anions by forming a new absorption band at 395 nm and new emission band at 495 nm, with the lowest detection limit of 2 μM. Based on these results, the anion/cation as well as cation/cation 2-to-1 encoder and 1-to-2 decoder have been formed. Moreover, a 4-to-2 encoder has also been established by using various cations as inputs.
