Precision Polymerization

The research projects in this cluster focus on the synthesis of novel, branched and dendritic polymer architectures, mostly based on -amino acid building blocks. The research projects do not aim at the synthesis of perfect (i.e. defect-free) dendrimers, but rather focus on the development of alternative, less time-consuming synthetic strategies towards branched polymer architectures. The interest in branched and dendritic poly(-amino acid)s (polypeptides) is two-fold. On the one hand, these compact, branched polymers may serve as structural mimics of globular proteins. On the other hand, highly-branched polypeptides may be interesting alternatives to perfect polypeptide dendrimers, which have received considerable attention as non-viral vectors for gene delivery and as platforms for the construction of magnetic resonance imaging agents.
