Description

有机发光器件 技术领域
本发明涉及一种有机发光器件的技术领域，特别是涉及一种其电荷传输层的分子共轭平面互相平行并垂直站立在电极上的有机发光器件。
 背景技术
有机发光器件（Organic Light-Emitting Diode，OLED）已成为新一代的平面显示器技术，其无需背光源，采用非常薄的有机材料涂层和玻璃基板，当有电流通过时，这些有机材料就会发光。
请参照图1所示，传统的OLED器件9由阳极91、空穴传输层93、发光层94、电子传输层95及阴极97组成。电子从阴极97注入到电子输运层95，空穴则由阳极91注入进空穴输运层93，它们在发光层94重新结合而发出光子。为了改善OLED器件9的性能，通常在阳极91与空穴传输层93之间插入一空穴注入层92，以有利于空穴注入进空穴输运层93，而在电子传输层95与阴极97之间插入一电子注入层96，以大幅降低阴极97与电子传输层95的能障，降低驱动电压。
目前，OLED器件的电荷传输层是通过蒸发源被加热蒸发后，在电极上冷凝形成无定形膜层。此类无定形膜传输电荷主要是通过电荷在分子之间跳跃完成，因此膜层内分子的组织形态是制约电荷重要因素。
请参照图2、图3及图4所示，其中图2为现有OLED器件的电荷传输层93(95)的膜层材料的分子结构，图3为图2中该分子结构的几何形状示意图，图4为现有OLED器件的电荷传输层93(95)的微观结构示意图。现有OLED器件的电荷传输层93(95)材料的分子结构均具有大共轭键，呈刚性平面结构，并且水平堆积于电极91(97)上而形成具有一定厚度的膜层，该膜层是由多个分子层90构成。详细地，在现有OLED器件的电荷传输层93(95)中，每个分子层90中的分子结构的长轴98（如图3）均平行于电极91(97)，虽然在每一分子层90内因有共轭键而具有高导电率，但是在电荷传输时，由于电荷传输方向A垂直于分子结构的长轴98，电荷必须克服分子层90之间的分子引力才能完成跃迁。因此，现有OLED器件的电荷传输层93(95)的电荷传输能力主要依赖电荷在分子层90之间的迁移，这种电荷传输层93(95)很难提高电荷的迁移率。
因此，有必要提供一种新的有机发光器件，以克服上述缺陷。

 本发明的最佳实施方式
为让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明如下。再者，本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参照图5所示，本发明OLED器件1主要包括阳极10、空穴传输层12、发光层14、电子传输层16及阴极18，其中空穴传输层12、发光层14、电子传输层16及阴极18是通过真空热蒸镀依次形成于阳极10上，并且各具有一定膜厚，其中形成电子传输层16的材料的分子结构具有大共轭键，呈刚性平面结构，且竖直堆积于阴极18上从而形成具有一定厚度的膜层。同样地，形成空穴传输层12的膜层材料的分子也是直立于阳极10上。
如图5所示，形成空穴传输层12与电子传输层16的膜层材料的分子长轴均垂直于阳极10与阴极18。因此，本发明OLED器件1的电荷传输就可以依赖膜层材料的分子的共轭键而非在分子之间的跳跃，从而提高电荷迁移率。
此外，本发明OLED器件1的电荷传输层（空穴传输层12与电子传输层16）是在不改变分子的平面结构基础上，使得膜层材料的分子均直立于电极（阳极10与阴极18）上，这样膜层中的每一分子层120、160的分子与分子之间形成很大的竖直的共轭平面，这些共轭平面互相平行且垂直站立于电极10、18上，使得电荷传输能够在共轭平面上传输。
本发明OLED器件1的电荷传输层12、16相较于现有的OLED器件9的电荷传输层93、95，在同等膜厚的条件下，本发明OLED器件1的电荷传输层12、16需要的分子层数量比较少，这样能够进一步减少电荷在分子之间的跳跃，从而进一步提高电荷迁移率。
请参照图6所示的本发明OLED器件1的另一实施例，本发明OLED器件1还包括有空穴注入层11及电子注入层17，其中空穴注入层11位于阳极10与空穴传输层12之间的空穴注入层11，而电子注入层17位于阴极18与电子传输层16之间的电子注入层17，从而进一步提高电荷迁移率。本发明空穴注入层11与电子注入层17的位置关系与图1所示的空穴注入层92与电子注入层96的位置关系相同。本发明OLED器件1的空穴注入层11与电子注入层17均采用与上述空穴传输层12及电子传输层16相同的膜层结构。亦即，形成空穴注入层11与电子注入层17的膜层材料的每一分子层110、170的分子与分子之间均形成一竖直的共轭平面，且这些共轭平面均互相平行并垂直于电极10、18。
更进一步地，本发明OLED器件1的空穴注入层11可以是单独蒸镀而成，也可以是与空穴传输层12的材料掺杂后蒸镀而成。同样地，本发明OLED器件1的电子注入层17也可以单独蒸镀，或与电子传输层16的材料掺杂后蒸镀而成。
本发明OLED器件1的电荷传输层12、16采用有机材料蒸镀而成，而有机分子则可以是联苯及其衍生物。
本发明OLED器件1的发光层14未采用以上膜层结构，而仍然采用分子水平堆积方式。
综上所述，本发明OLED器件1的电荷传输层12、16中的分子长轴98（如图3所示）均直立于电极10、18上，电荷传输主要依赖分子内的共轭键，而非分子之间的跳跃，从而能够有效地提高电荷迁移率，降低OLED的工作电压和功耗，提高OLED性能。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
