Synthesis Materials

Synthesis and characterization of new organic pigments of natural origin based on the hydrogen bond

The main goal of this research line is to produce high-performance electronics (organic thin film transistors, OTFTs and circuits) that are fully biodegradable in a controllable manner when their life cycle is considered over. Within this line of research are investigated innovative synthetic approaches to epindolidione synthesis and some of its derivatives, materials that are used in organic field effect transistors (OFET) that are both highly efficient and biodegradable at the end of their lifecycle.

Development of new organometallic methodologies for obtaining poly(arylenes) through a “chain growth mechanism”

Conjugated polymers are the active materials of a wide number of smart devices. In this perspective, the availability of “sharp” synthetic tools for the controlled obtainment of conjugated organic polymers is a truly pressing issue since polymer-based device performancesis strongly affected by molecular weight, dispersity and regularity. In this perspective, our efforts are directed to the study of C-C coupling polymerisation reactions of suitable AB-type monomers via a chain-growth mechanism ensuring the necessary control over the molecular weights and polydispersities to the target materials.

Synthesis of holte transporters for Perovskite solar cells.

Since the emergence of Perovskite Solar Cells (PSC) as highly promising photovoltaics, a great effort has been devoted to develop innovative and more efficient materials specifically designed for this architecture. Concerning Hole Transporting Material (HTM) for PSCs, the high synthesis cost of Spiro-OMeTAD and its low charge-carrier mobility jeopardize its commercial-scale application. Our work is devoted to the synthetic engineer of the photoelectrical properties of organic molecules as the way to find new suitable HTM candidates for high-performance PSCs.
