Patent ID: 8324616

Claim:
An optoelectronic device comprising: a first electrode; an active layer disposed on the first electrode; a second electrode disposed on the active layer; and a self-assembled monolayer interposed between the first electrode and the active layer, interposed between the active layer and the second electrode, or disposed inside the active layer, wherein the self-assembled monolayer comprises a first compound and a second compound having different functional groups from each other, and wherein the first compound and the second compound are independently represented by the following Chemical Formulas 1 and 2: *-A 1 -B 1 -X 1 Chemical Formula 1 *-A 2 -B 2 -X 2 Chemical Formula 2 wherein, in the above Chemical Formulas 1 and 2, A 1 and A 2 are the same or different, and are independently selected from the group consisting of a thiol derivative, an alcohol derivative, and alkoxysilane derivative, a halosilane derivative, a carboxylic acid derivative, and a combination thereof, B 1 and B 2 are the same or different, and are independently selected from the group consisting of a single bond, a substituted or unsubstituted C 1 to C 30 alkylene, a substituted or unsubstituted C 1 to C 30 alkenylene, a substituted or unsubstituted C 1 to C 30 alkynylene, a derivative thereof, and a combination thereof, and X 1 and X 2 are functional groups that are different from each other, and are independently selected from the group consisting of hydrogen, a substituted or unsubstituted C 1 to C 30 alkyl, a substituted or unsubstituted C 2 to C 30 alkenyl, a substituted or unsubstituted C 2 to C 30 alkynyl, a substituted or unsubstituted C 3 to C 30 cycloalkyl, a substituted or unsubstituted C 3 to C 30 cycloalkenyl, a substituted or unsubstituted C 5 to C 30 cycloalkynyl, a substituted or unsubstituted C 1 to C 30 alkoxy, a substituted or unsubstituted C 1 to C 30 carbonyl, a substituted or unsubstituted C 1 to C 30 carboxyl, a substituted or unsubstituted C 2 to C 30 (meth) acrylate, a substituted or unsubstituted C 2 to C 30 epoxy, a substituted or unsubstituted C 6 to C 30 aromatic group, a substituted or unsubstituted C 3 to C 30 heterocyclic group, a thiol, a hydroxy, an amine, a nitro, a cyano, a halogen, a derivative thereof, and a combination thereof.
