Cathode Interlayer Materials (CIMs), Materials, Organic Conductors
PDINO (CAS number 1558023-86-1), bearing amino N-oxide group on perylenediimide (PDI) with π-delocalized planar structures and high electron affinities, is widely used as cathode interlayer materials. While working great with Al as the cathode, PDINO also allows high work function metals (such as Au and Ag) to act as efficient cathodes.
With a measured conductivity of 7.6 × 10-5 S/cm, PDINO has four orders of magnitude higher than that of the well-known cathode interlayer PFN (6.9 × 10-9 S/cm). Organic photovoltaic cell with 17% efficiency was achieved with PDINO as the cathode interlayer material by employing PBDB-TF (PM6):BTP-4Cl-12 (Y7-BO) as the active layer.
