Dendritic molecule containing metal phthalocyanine, method of preparing the same and organic light emitting diode comprising the dendritic molecule
摘要：
A dendritic molecule represented by Formula 3: where Pc is metal phthalocyanine represented by Formula 2: where M is a core metal of the dendritic molecule; n is an integer in the range of 1 to 50; each of the Xs is a bivalent linking group independently selected from the group consisting of O, S, CH2, CO, SO2 and NHCO; and each of the Rs is independently selected from the group consisting of CN, COOH, SO3H and PO3H. The dendritic molecule containing metal phthalocyanine is dissolved in an organic solvent, and thus can be used to easily form a hole injection layer or a hole transport layer using solution deposition. The hole injection layer comprising the dendritic molecule containing metal phthalocyanine has good adhesion to an electrode and improved hole injection ability. The organic light emitting diode including the hole injection layer exhibits high luminance and emitting efficiency.
摘要（中）：

由式3表示的树枝状分子：其中Pc是由式2表示的金属酞菁：其中M是树枝状分子的核心金属; n为1〜50的整数， 每个X是独立地选自O，S，CH 2，CO，SO 2和NHCO的二价连接基团; 并且每个R a独立地选自CN，COOH，SO 3 H和PO 3 H。 将含有金属酞菁的树枝状分子溶解在有机溶剂中，因此可以容易地使用溶液沉积形成空穴注入层或空穴传输层。 包含含有金属酞菁的枝状分子的空穴注入层对电极具有良好的粘附性和改善的空穴注入能力。 包含空穴注入层的有机发光二极管具有高的亮度和发光效率。
