Organic, Polymer, and Supramolecular Chemistry
The Rudick lab is interested in strategies to minimize or even eliminate heterogeneity
in multifunctional materials. Heterogeneity in multifunctional polymers and nanoparticles
complicates the interpretation of structure-property relationships and can lead to
batch-to-batch variability in properties. Several types of heterogeneity arise in
polymers made up from different functional monomers including: (i) chain length (or
molecular weight) dispersity, (ii) non-uniformity of monomer sequence, and (iii) differences
in the ratio of monomers incorporated in each polymer molecule. Existing analytical
tools are insufficient to characterize these complex mixtures, so we are exploring
synthetic and supramolecular chemistry approaches to tame the complexity of multifunctional
materials. Strategies for controlling either the ratio or arrangement of the monomers can yield
materials with highly tailored properties or properties that are unique from those
of heterogeneous polymer materials.
Multicomponent Reactions as Methods for Controlled Multifunctionalization
Multicomponent reactions combine three different reactants into a single product,
which is advantageous for the synthesis of multifunctional materials. We have shown
that the Passerini three-component reaction can be used to control the ratio of functional
subunits in three-arm star-branched liquid crystals (Org. Lett. 2015) as well as in dendritic polymers (Org. Lett. 2012; Chem. Commun. 2015). Additionally, multicomponent reactions offer advantages such as efficiency and
versatility. We are exploiting the advantages of multicomponent reactions to explore
properties that are unique to these well-defined multifunctional materials.
Self-Assembly and Self-Organization of Peptide-Dendron Hybrids
Iterative synthesis methods have enabled the synthesis of monodisperse and sequence-defined
macromolecules such as peptides and dendrimers. Combining the diverse physical properties
that are available to different dendrimers with the folding and self-assembly behaviors
of peptides yields hybrid biomaterials whose properties can be tailored with exceptional
precision. We have developed a convenient and bioorthogonal approach grafting dendrons
to peptides (Biopolymers 2015). We have shown that protein design principles can be applied to the design of peptide-dendron
hybrids that self-assemble into dendronized helix bundle motifs (Chem. Commun. 2015; Biomacromolecules 2016).
