• according to well-established protocols [65]. Consequently, we adopted the Sharpless–Fokin modification for the Huisgen azide–alkyne cycloaddition [66] to achieve the final immobilization of the modified imidazolidin-4-one onto the hyperbranched polymer and on the G1 dendron [65]. The progress of the

• very regular (Figure 2B and C). Furthermore, as seen in Figure 2B and C, larger aggregates were formed due to the attachment of the HBPCSi segments and β-CD moieties. Large second aggregates from hyperbranched, polymer-based copolymers were also observed by Hong et al. [25]. However, the irregular
