Abstract

A novel UV-visible chemosensor, 4-methyl-2-((quinolinyl-8-amino)methyl)phenol (MQAMP), was designed and synthesized. The spectral properties of its free and Cu²⁺-coordinated forms were characterized. Under the optimized conditions, MQAMP showed selective and sensitive sensing for copper ions in an ethanol solution. The binding of Cu²⁺ to MQAMP caused a marked enhancement of the absorbance, and an about 100 nm red-shift of the maximum absorption wavelength. Other ions including Mo⁶⁺, Li⁺, Cs⁺, As³⁺, Ca²⁺, Na⁺, Cd²⁺, K⁺, Mg²⁺, Pt²⁺, Sr²⁺, Ba²⁺, Al³⁺, Cr⁶⁺, Be²⁺, Fe³⁺, Ni²⁺, F^-, CH₃COO^-, SO₄^2-, NO₃^-, Cl^-, CO₃^2-, and SO₃^2- displayed no significant interference in this detection of Cu²⁺. The chemosensor exhibited a dynamic response range for Cu²⁺ from 1.0 × 10^-6 to 1.0 × 10^-5 mol L^-1 with a detection limit of 1.1 × 10^-7 mol L^-1 (3σ).
