We investigate exciton delocalization and dissociation in non-entangled conjugated bottlebrushes and polyelectrolytes.
Novel non-entangled conjugated bottlebrush copolymers and mixed ion-electron conductors will be synthesized and the influence of external stimuli such as electric field, electrolyte medium and doping on structural features, exciton delocalization as well as transport will be studied using NEXAFS spectroscopy, in situ GIWAXS and optical spectroscopy.

We focus on the synthetical aspects of next generation conjugated polymers with diverse polymer topology as well as mixed ionic electronic transport properties for bioelectronics.
Simultaneous volumetric ion and electron conduction in these materials enable high signal amplification in electrochemical transistors.
The basic structural features as well as charge transport properties will be elucidated both in the dry as well as in the swollen state in aqueous medium to understand the device characteristics in electrochemical transistors.
In a collaboration with Monash University and Australian Synchrotron detailed thin film morphology and orientation will be studied.
