Thesis Subject

High-areal density of nanohelices formed by chiral block copolymers
The helical architecture is one of the most fascinating structures owing to the absence of mirror reflection symmetry (i.e., the concept of chirality) that is a highly functional feature observed at both microscopic and macroscopic levels in nature. So far, artificial helical nanostructures have been mostly generated through self-assembling processes by using specifically devised chiral building blocks. However, highly relevant fabrication challenges such as the precise positioning and ordering of chiral features, the control of their characteristic length-scale and the fine-tuning of their self-assembly still need to be addressed in order to fully apprehend their potential in targeted applications (see Figure below). Accordingly, this research project aims at studying the homochiral evolution at different length scales (i.e., from the monomeric to nanodomain level) during the self-assembly process to produce well-defined helical structures with a preferred chirality. We will then explore templated synthesis methods to (anti-)replicate the hierarchical chiral superstructures into functional oxides or metals towards the generation of optically-active surfaces. Finally, the chirality transfer and the related optical properties will be probed to fully establish the design rules and processes towards practical applications.

Your Work Environment

The Laboratory of Organic Polymer Chemistry (LCPO) is a joint research unit affiliated with the CNRS, the University of Bordeaux, and the Bordeaux Polytechnic Institute (http://www.lcpo.fr). The LCPO is organized into four research teams and comprises nearly 150 members, including approximately 50 permanent staff. With more than 30 years of expertise in polymer chemistry, the LCPO conducts research aimed at:
- developing innovative methodologies for precision polymer synthesis, notably using biomimetic approaches and/or principles of green chemistry;
- designing functional polymer materials through macromolecular engineering and self-assembly, particularly in the fields of renewable materials, health, and energy;
- establishing and strengthening long-term partnerships with the socio-economic sector.
