Benzo-condensed dithieno[3,2-b:2′,3′-d]phospholes were synthesized that allow convenient tuning of properties that are essential for application as semiconductor materials in organic field-effect transistor (OFET) devices. The versatile reactivity of the trivalent P atom in these heteropentacenes provides access to materials that show different photophys. properties, significantly different organization in the solid state, and distinctly different electrochem. properties that can be achieved by simple chem. modifications. The materials show strong photoluminescence in solution and in the solid state that depends on the electronic nature of the P center. Electrochem. studies revealed that the P atom intrinsically furnishes materials with n-channel or ambipolar behavior, also depending on its electronic nature. The exptl. data were verified by DFT quantum chem. calculations and suggest that the P-based heteropentacenes could be excellent candidates for n-channel OFET semiconductor materials. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Recommanded Product: 6287-82-7).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, sertaconazole, and also BTCP.Recommanded Product: 6287-82-7
