dc.description.abstractBrownian dynamics simulation is conducted to investigate the dynamics of dendrimer-polymer conjugates on the basis of a coarse-grained bead-spring model. The grafted polymers are found to slow the global dynamics of the dendrimer core. Because of the structural difference between the two moieties, the translational and rotational diffusivities of a conjugate show different scaling behaviors from those for a dendrimer, but in principle follow a Stokes-Einstein fashion, analogous to polymers of other types. When the grafted chains are long enough, they become brushlike, evidenced by the scaling behavior of the end-to-end distance as well as the chain-length dependence of the rotational relaxation time. For the range of chain length investigated, it is found that the brushlike grafted polymers still fall within the dilute regime. Thereby the interchain interactions are not strong enough to render a change in the scaling behavior of rotation relaxation in comparison with an isolated rodlike polymer. © 2006 American Chemical Society.
