Welcome

The Peeks group employs rational molecular design to build new materials, with a focus on exploring supramolecular and macromolecular chemistry towards sensing and light-harvesting applications. Scroll through this page to learn more!

We are based in the School of Chemistry at UNSW Sydney.

Self-assembly fundamentals

Nature is an expert at self-assembly. Your body, as a whole, is a complex compartmentalised system of molecules, reactions, and replicators, all underpinned by self-assembly and supramolecular chemistry.

Faraday rotation in organic materials

All matter exhibits a Faraday effect: the polarisation of light as it passes through a material changes proportional to the strength of an external magnetic field.

Aromaticity and antiaromaticity

Aromatic molecules are cyclic and pi-conjugated, and exhibit some interesting effects. Most well-known nowadays is the behaviour of aromatic molecules in a magnetic field: in an NMR spectrometer, we see that the chemical shifts of protons inside and outside the ring are anamolously (de)shielded.
