Abstract

Abstract: An amphiphilic polymer containing adenine, poly[(polyoxyethylene-600)-oxy-5-[6-(1-adenine) hexyl] isophthaloyl(PPEAHI), was synthesized. The self-organized behavior of the amphiphilic polymer in dilute aqueous solution was studied. The morphology of the aggregates was observed via SEM. The result indicates that the amphiphilic PPEAHI polymer is self-organized into nanospheres in dilute aqueous solution. The molecular recognition between adenine in PPEAHI polymer and thymine substrate was studied via FTIR, which implied that the hydrogen bonds were formed between complemenntary groups. The formation of H-bonds was further confirmed by variable temperature FTIR.

Key words: Amphiphilic polymer, Nanosphere, Nucleobase, Molecular recognition
