Organic devices, organic electroluminescent devices and organic solar cells
An organic device, including an organic compound having charge-transporting ability (i.e., transporting holes and/or electrons) and/or including organic light emissive molecules capable of emitting at least one of fluorescent light or phosphorescent light, has a charge transfer complex-contained layer including a charge transfer complex formed upon contact of an organic hole-transporting compound and molybdenum trioxide via a manner of lamination or mixing thereof, so that the organic hole-transporting compound is in a state of radical cation (i.e., positively charged species) in the charge transfer complex-contained layer.
1. An organic device having a layer structure on a substrate in the following deposition sequence:
(A) a cathode layer;
(B) a layer structure mainly consisting of organic compounds;
(C)a substantially transparent anode-adjacent layer consisting of a mixture of MoO 3 and an organic hole-transporting molecule consisting essentially of alpha-NPD;
(D) an anode layer;
wherein “(C) the substantially transparent anode-adjacent layer consisting of a mixture of MoO 3 and an organic hole-transporting molecule” is prepared via resistive heating method deposited in a molar ratio of 5:1, and,
wherein the MoO 3 and the organic hole-transporting molecule in the “(C) the substantially transparent anode-adjacent layer” forms the charge transfer complex, thus the organic hole-transporting molecule is in the state of radical cations, forming the charge transfer complex contained layer.
