|Abstract: ||The synthesis of nucleobase-containing polymers was successfully performed by RAFT dispersion
polymerization in both chloroform and 1,4-dioxane and self-assembly was induced by the polymerizations.
A combination of scattering and microscopy techniques were used to characterize the morphologies.
It is found that the morphologies of self-assembled nucleobase-containing polymers are
solvent dependent. By varying the DP of the core-forming block, only spherical micelles with internal
structures were obtained in chloroform when using only adenine-containing methacrylate or a mixture of
adenine-containing methacrylate and thymine-containing methacrylate as monomers. However, higher
order structures and morphology transitions were observed in 1,4-dioxane. A sphere-rod-lamella-twisted
bilayer transition was observed in this study. Moreover, the kinetics of the dispersion polymerizations were
studied in both solvents, suggesting a different formation mechanism in these systems.|
