Main research topics

My research career has been inspired mainly by two fascinating scientific fields: supramolecular chemistry and organic electronics. The combination of both has given rise to supramolecular electronics, which bridges the gap between molecular and plastic electronics, through the formation of supramolecular semiconducting structures. In this sense, supramolecular chemistry provides the tools to achieve highly organized structures with superior properties than those of the monomers. The supramolecular structures arise through reversible bonds, such as hydrogen-bonding and or/ other noncovalent interactions, establishing supramolecular order at the required scale for the operation of organic electronic devices. Apart from attaining the required structures for electronic communication, the molecular design is equally important. Not only molecules with appropriate optoelectronic properties should be designed, but they should have the ability to self-assemble into challenging shapes and dimensions. More recently, our research efforts are focused on contributing with solutions to the threatening energy crisis. Particularly, we want to contribute by reducing some of the key problems found in organic photovoltaic devices. To do this, we have imported the Chiral Induced Spin Selectivity (CISS) effect from the field of spintronics and we are introducing it into chiral supramolecular structures. In this case, supramolecular chemistry meets the power of chirality to provide directionality to charges and increase photovoltaic device efficiency.

I completed my thesis on the preparation of systems with multiple hydrogen bonds and self-assembly of pi-conjugated systems templated by DNA. Then, I continued my research at the interface of chemistry and physical-chemistry. During my postdoc in Northwestern University (Chicago, USA), I worked on the fabrication of organic solar cells using hydrogen-bonded semiconductors. These studies showed that it is possible to increase the efficiency of solar cells by 50% when hydrogen bonds are present in the molecular structure of the semiconductors. However, there is still no clear answer regarding the advantages of hydrogen bonds in organic photovoltaics. Since my recruitment at the CNRS in 2015 (although I officially started in 2016), I continued my research in the field of hydrogen-bonded semiconducting materials and I have started a systematic study to know the influence of multiple parameters in the formation of hydrogen-bonding and their impact in organic electronic devices. Thanks to the funding I obtained (see below), it was possible to put together a great group of young researchers, PhDs and postdocs, who are working very hard to demonstrate the powerful effect of supramolecular chemistry in the field of organic electronics. All our work is very important to pursue a long-term scientific goal: improving organic electronic devices from the supramolecular level and contribute with alternatives to the energy crisis.

We are very lucky to collaborate with very inspirational researchers, not only from our institute, but also from France, Europe and the rest of the world (see below).

I am currently the head of the SYCOMMOR team (since October 2022) and I hope to continue keeping the cohesion of the group, the interactions among all the members, improving the education of young researchers and making our team very inclusive, where all of us have the best opportunities to pursue our research.
