A method for fabricating an organic light emitting diode and a device thereof are provided. The method includes: providing a substrate; dispensing to the substrate a second organic molecule solution resulting from dissolving a second organic molecule in a solvent; applying the second organic molecule solution to a surface of the substrate so as to form a wet film layer; and heating the wet film layer by a heating unit to remove the solvent therefrom and thereby form a second organic molecule film. The method is effective in fabricating a uniform multilayer structure for use in fabrication of large-area photoelectric components.

The present invention provides compound of formula (I)wherein each substituent is defined in the specification. The compound may be used, in combination with other organic light-emitting materials, in a light-emitting layer of an organic light-emitting element. The present invention also provides an organic light-emitting element including a first electrode, a second electrode and at least three layers of organic material layers disposed between the first electrode and the second electrode, wherein the layer used as a light-emitting layer contains a compound of formula (I). Further, an all-solution process, which is used for fabricating the organic light-emitting element of the present invention, has the advantages such as avoiding miscibility among the layers to fabricate an element with a large surface area and lower production cost.

An organic photosensitive optoelectronic device includes an anode, an organic photosensitive layer formed on the anode and having a donor portion and an acceptor portion, a hole blocking layer formed on the organic photosensitive layer so as for the organic photosensitive layer to be sandwiched between the anode and the hole blocking layer, and a cathode formed on the hole blocking layer so as for the hole blocking layer to be sandwiched between the cathode and the organic photosensitive layer. The highest occupied molecular orbitals (HOMO) of the hole blocking layer is at least 0.3 eV higher than that of the donor portion. Therefore, the optoelectronic device efficiently suppresses dark current so as to enhance sensitivity when applied to a detector.
