Abstract: A new 1-naphthalenamine (NNA) specific molecularly imprinted polymer (MIP) was synthesized based on non-covalent interaction. The molecular recognition characteristics of the template polymer were evaluated by UV, IR, XPS and 1H NMR. The NNA-MAA complexes of 1:1 mole ratio were obtained by nitrogen bonding and the complexes possessed better stabilization (K = 5.537 x 10^4 L/mol). Furthermore, hydrogen atom of the amino group in 1-naphthalenamine is hydrogen-bond acceptors. Hydrogen atom of the lactam group in methacrylic acid is hydrogen-bond donor, being the predominant binding sites interacting with 1-naphthalenamine. The adsorption characteristics of MIP was evaluated by equilibrium adsorption experiment. The results indicate that MIP performs highly selectivity to 1-naphthalenamine.
