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 Cu ion. Preliminary, solvent effect, metal selectivity and metal ligand ratio were analyzed through UV-Visible study. Fluorescence response toward Cu was carried to assess the fluorescent property of synthesized Schiff base. The probe exhibited a higher fluorescence enhancement in the presence of Cu over other metal ions (Ni, Zn, Hg, Co, Cd, Al, Fe, and Pb). The binding stoichiometry between L and Cu has been investigated using Job's plot and Benesi-Hildebrand equation and it was found that ligand L can form 1:1 L-Cu complex with binding constant (K ) of 4 × 10 LM.
在本研究中,我们报道了新型席夫碱E-1-(((1-苄基哌啶-4-基)亚氨基)甲基)萘-2-醇(L)的合成及其对铜离子的荧光响应评估。通过紫外可见光谱研究初步分析了溶剂效应、金属选择性和金属配体比例。对铜进行荧光响应以评估合成席夫碱的荧光性质。该探针在铜存在下比其他金属离子(镍、锌、汞、钴、镉、铝、铁和铅)表现出更高的荧光增强。使用乔布曲线和贝内西-希尔德布兰德方程研究了L与铜之间的结合化学计量,发现配体L可以形成1:1的L-Cu配合物,结合常数(K)为4×10 LM。
