The Roza Szweda Research Group

Programmable Polymers Center

We are developing molecular codes that program the folding, assembly and function of abiotic polymers

Molecular Coding in Abiotic Polymers

We investigate how sequence, stereochemistry, side-chain interactions and environment act as molecular codes that program the behaviour of synthetic macromolecules.

Our goal is to establish design rules connecting:

molecular code → conformational ensemble → self-assembly → material properties → function

Using sequence-defined and stereocontrolled oligourethanes as precise molecular platforms, we develop scalable synthetic methods and study how local molecular information is propagated across length scales.

Our research

Programming molecular folding

We determine how stereochemical sequence, monomer order, chain length, side-chain chemistry and solvent control the conformational ensembles of abiotic oligomers.

Directing self-assembly

We investigate how molecular information determines whether an oligomer folds intramolecularly, associates into supramolecular structures, forms gels or remains soluble.

Translating molecular information into function

We use encoded conformations to develop catalytic systems, selective sensors, responsive interfaces and polymer materials with discrete, sequence-defined side chains.

From precision synthesis to programmable materials

Our scalable one-pot synthesis provides access to sequence- and stereo-defined oligourethanes in quantities sufficient for systematic structural studies and materials development.

This platform enabled the progression from discrete oligomers to folding systems, supramolecular assemblies and poly(oligourethane methacrylate) bottlebrushes.

Our vision

We aim to move synthetic polymers beyond statistical structure–property relationships toward systems whose conformations, interactions and functions can be predicted and programmed from their molecular code.
