title: A New Piperidine Derivatized-Schiff Base Based "Turn-on" Cu2+Chemo-Sensor.
abstract: In this study, we report the synthesis of new Schiff base E-1-(((1-benzylpiperidin-4-yl)imino)methyl)naphthalenee-2-ol (L) and evaluation of its fluorescence response toward Cu2+ion. Preliminary, solvent effect, metal selectivity and metal ligand ratio were analyzed through UV-Visible study. Fluorescence response toward Cu2+was carried to assess the fluorescent property of synthesized Schiff base. The probe exhibited a higher fluorescence enhancement in the presence of Cu2+over other metal ions (Ni2+, Zn2+, Hg2+, Co2+, Cd2+, Al3+, Fe2+, and Pb2+). The binding stoichiometry between L and Cu2+has been investigated using Job's plot and Benesi-Hildebrand equation and it was found that ligand L can form 1:1 L-Cu2+complex with binding constant (Ka) of 4 × 104LM-1.
