Zang, Minghui published the artcileStudy on the synthesis, self-assembly and responsive behavior of azobenzene triblock copolymers, COA of Formula: C23H28N2O4, the publication is Zhongguo Keji Lunwen (2014), 9(6), 648-653, database is CAplus.
A new triblock copolymer poly(ethylene oxide)monomethyl ether-b-poly(acrylic aid)-b-poly[6-(4-methoxy-azobenzene-4′-oxy)hexyl methylacrylic acid] was synthesized by the atom transfer radical polymerization (ATRP) method. The self-assembly behaviors in aqueous media, pH value and photo-sensitive properties of this copolymer were studied by the means of transmission electron microscopy (TEM), SEM (SEM), laser light scattering (LLS) and UV-Vis spectrophotometer. It was found that the copolymer could self-assemble into vesicle structure. With decreasing the pH value, the particle size of the micelles increased sharply obviously bigger when pH<3.4; however, there was not significant change for the particle size of micelles when pH>3.4. Under the irradiation of polarized light, the aggregates were elongated with increasing the irradiation time.
