PDINN, used to improve device stability in non-fullerene OSCs
High quality material available online (or request a quote) for priority dispatch
PDINN (CAS number 1020180-01-1), while compared with PDINO, can provide better contact with the electrodes and non-fullerene active layers to give higher conductivity. PDINN also can reduce the work functions (WFs) of the metal cathode, making it a better candidate to use as cathode interlayer materials (CIMs) in non-fullerene OSCs with air stable metal cathode, such as Ag and Cu, to improve the device stability.
With solubility of 26.7 mg/ml in methanol without any assistance from acetic acid, PDINN has better solubility than most of the CIMs such as PFN and PDIN which needs acetic acid to make a clear solution. PDINN also shows a better interfacial compatibility to a wider range of active layer materials to form better quality films for OSCs devices than PDINO.
