Formation of multicore structures in single dendritic-linear copolymers — •Martin Wengenmayr1,2, Ron Dockhorn1,2, and Jens-Uwe Sommer1,21Leibniz-Institut für Polymerforschung Dresden, Germany — 2Technische Universität Dresden, Germany

Dendritic polymers gain attention for promising applications in drug delivery purposes or as catalysts. Usually the dendritic part will be rather hydrophobic and has the tendency to collapse in aqueous environment. Hydrophilic chains attached to the terminal groups form a corona being reminiscent to a polymer micelle. We investigate the conformational and thermodynamic properties of these molecules by analytical models and computer simulations. A mean-field model applying the Daoud-Cotton approach and a surface tension argument is presented and suggests the splitting of the unimolecular single-core structure into a multicore structure with increasing dendrimers generation and decreasing solvent selectivity. Monte Carlo simulations utilizing the bond fluctuation model with explicit solvent are performed which show the formation of multicore structures for trifunctional codendrimers. These findings are aimed to understand the physics of spontaneous self-assembly of co-dendrimers in various well-defined macro-conformations under change of environmental conditions.
