摘要
A novel optical chemical sensor L was designed and synthesized for the determination of silver ions. The sensor L was derived from 1-naphthaldehyde and 3,4,5-tris(hexadecyloxy)benzohydrazide. The sensor L shows high sensitivity and selectivity for Ag+ detection in comparison to other metal cations (Mg2+, Ca2+, Al3+, Cr3+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+) and has no significant response to other common metal cations. Upon addition of Ag+, the fluorescent emission of the sensor L was enhanced dramatically but other metal cations had no same response. The detection limit for Ag+ was 1.2x10(-7) mol/L. Therefore, the sensor L is useful for Ag+ detection with some advantages including sensitivity, selectivity, simplicity and low-cost.
