US 2008/0290338 A1 · Hyperbranched polymer, organic light-emitting diode including organic layer including the hyperbranched polymer, and method of manufacturing the organic light-emitting diode

Abstract

Provided are a hyperbranched polymer represented by Formula 1 below, an organic light-emitting diode including an organic layer including the hyperbranched polymer, and a method of manufacturing the organic light-emitting diode: For a detailed description about Formula 1, the Detailed Description of the Invention may be referred to. The hyperbranched polymer is excellent in view of hole injection capability and/or electron blocking capability and adhesion with an electrode, and thus, the organic light-emitting diode including the organic layer including the hyperbranched polymer can have good electrical properties.
