The Calvino group is interested in adressing the enviromental issue related to the limited renewability of crosslinked polymer materials. Thanks to high availability, environmental-friendliness and ability to trigger specific chemical reactions, we chose light as a central point of our studies. Noticeably, coumarine and its analogues are known to undergo a reversible light-mediated dimerisation and reversion. Based on this idea, my project consists in synthesising, testing and optimising the photochemical performances of such photosensitive motifs, implementing them in polymer matrices and optimising the parameters of the corresponding fabrication procedures. Ultimately, I aim to demonstrate that coumarine analogues can be used to access high molecular weight polymer material by light-trigerred step growth polymerization of telechelic oligomer. I want to show that the so-obtained polymer materials can be efficiently renewed on-demand into their initial constituents using a dissimilar irradiation.
