Low price, high purity IDIC-4F available to buy online

Electron acceptor able to give a device performance efficiency of over 12.1%

IDIC-4F, a fluorinated analog of IDIC, shows an A-D-A type structure. The structure has an electron-donating fused five-member-ring indaceno[1,2-b:5,6-b′]dithiophene (IDT) core, terminated by two electron-withdrawing units, 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (IC-2F).

All small molecule organic solar cells (SM-OSCs) with H14 as a small molecule donor and IDIC-4F as electron acceptor have an easy to fabricate and simple structure. Such devices have been shown to give a device performance efficiency over 12.1% which is the highest efficiency reported for IDIC-4F-based SM-OSCs.
