H-1 NMR study of self-assembly of Dendr. PE-PAA, an amphiphilic block copolymer in aqueous solution

The behavior of a novel amphiphilic block copolymer, Dendr. PE-PAA, in aqueous solution was studied by H-1 NMR. The self-diffusion, spin-lattice relaxation time, spin-spin relaxation time and NOESY spectra were obtained. The results suggest that the amphiphilic block copolymer forms self-assembly in aqueous solution, and reveal that the shapes of self-assembly change with different concentration of the solution.
