Researchers from Japan's National Institute for Materials Science (NIMS) and Germany's Max Planck Institute developed a new 2D organic material made from thiopene. Thiophene has been already been suggested for several applications (including OLED panels, OPVs and field effect transistors). This is the first time that a simple and efficient production process (solution-based with high crystallinity) for thiopnene has been developed.
Using an alternating copolymer (which is made from thiophene derivative and flexible ethylene glycol chains) and then folding it in organic solvents in a specific makes the material self-assemble in 2D sheets. This method will hopefully lead to a simple and efficient way to fabricate such sheets.
