Self-Assembled Nanodielectrics (SANDs) for Unconventional Electronics

Synthetic Strategy for Large Scale Production of Oligothiophenes

Oligothiophenes are important organic electronic materials which can be produced using synthetic intermediates and Suzuki coupling.

Development of organic semiconductors from highly ordered oligo and polythiophenes

The soaring global demand for energy, coupled with the limited supply of fossil fuels, has increased the need for renewable, low-cost energy sources. Organic electronics have shown great promise for applications in lighting, power, and circuitry, with rapidly improving performance already surpassing that of amorphous silicon-based counterparts.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
