Definitions
- the optically active layer is expediently composed of several layers, at least one layer specifically for hole formation (hole injection layer, HIL) or for hole conduction (hole transport layer, HTL) and another layer are trained in particular for electron release layer (EIL), for electron transport layer (ETL) or for light emission (emission layer, EML).
- the known structure of such OLEDs provides a glass substrate on which a transparent anode made of a transparent conductive oxide
- TCO indium tin oxide
- HIL indium tin oxide
- EML EML
- ETL ETL
- EIL metallic cathode
- OLEDs of the known type are either made only from layers of different small molecules (SM-OLED, small molecule OLED) or from different polymers (PM- OLED), the small molecules are successively applied as thin layers on the substrate by vacuum sublimation, whereas polymers are processed from a solution (water or organic solvent), polymer layers offer particular advantages as HIL and HTL, since they show good hole transport properties
- SM-OLED small molecule OLED
- PM- OLED polymers
- HIL and HTL since they show good hole transport properties
- Molecules which are suitable as HILs are, for example, anthracene, tetracene and pentacene (cf. EP 0 278 758 B1).
- the layers of the OLEDs are highly susceptible to moisture, so that after the application of the second electrode, the OLEDs are encapsulated in such a way that only connections of the electrodes are accessible.
- Small molecules are therefore organic molecules that do not form chains or networks through polymerization.
- the present invention is therefore based on the object of eliminating or at least reducing the restrictions on the structure of electrical components made of organic substances due to moisture sensitivity and diffusion phenomena.
- This object is surprisingly achieved by using a layer of hydrophobic, linear or two-dimensional polycyclic aromatics with three to twelve ring structures, including metal-containing or metal-free phthalocyanines, which are residual groups - H and / or -F, alkyl groups, aryl groups and / or fluorinated hydrocarbons have, as a barrier layer in or as an encapsulation of electrical components constructed with organic layers.
- the present invention is based on the knowledge that the layers mentioned, in particular and preferably made of pentacene, can not only be a functional layer in the construction of organic electrical components, but also unexpectedly has barrier properties which make it possible to counteract the corresponding layer as a barrier layer Use moisture to protect the underlying layers and the metallic cathode.
- the layer used according to the invention is preferably made of a material from the group consisting of anthracene, phenanthrene, tetracene, chrysene, pentacene, hexacene, perylene, triphenylene, corones, m-naphthodianthracene, m-anthracenoditetracene, m-tetracenodipentacene, pyrene, benzopyrene, ovals, violanthrene and Derivatives of the aforementioned substances with residual groups -H and / or -F, alkyl groups, aryl groups and / or fluorinated hydrocarbons is formed.
- each R is an -H and / or -F and / or an alkyl group and / or an aryl group and / or a can be fluorinated hydrocarbon. In all cases it is preferred if the number of ring structures of the aromatic is between 5 and 10, preferably between 4 and 10, preferably between 5 and 8.
- organic electrical components can be constructed in which the layer both fulfills an electrical function and is constructed as a barrier layer or as an in-situ encapsulation.
- an organic light-emitting diode with a substrate, a first electrode applied to the substrate, at least one electron-injecting and transporting zone, at least one hole-injecting and transporting zone and a second electrode is characterized in that the hole-injecting and transporting zone is a layer of linear or two-dimensionally linked polycyclic aromatics with 3 to 12 ring structures, including metal-containing or metal-free phthalocyanines which have -H and / or -F, alkyl groups, aryl groups and / or fluorinated hydrocarbons as residual groups, this layer being designed as an encapsulation layer.
- the layer structure is designed so that the layer covers all moisture-sensitive layers that have been built up beforehand.
- the invention further enables an organic light-emitting diode with a substrate, a cathode applied to the substrate, at least one electron-injecting and transporting zone, at least a hole-injecting and transporting zone and a translucent anode, the electron-injecting and transporting zone being built up with small molecules and attached to it a layer of linearly or two-dimensionally linked polycyclic aromatics with 3 to 12 ring structures, including metal-containing or metal-free phthalocyanines, which act as residual groups -H and / or -F, alkyl groups, aryl groups and / or fluorinated hydrocarbons connected to the anode.
- the present invention therefore also enables an organic light-emitting diode (OLED) constructed in a hybrid structure, in which the radiation is “upward”, that is to say away from the substrate side.
- OLED organic light-emitting diode
- the invention enables an optimized structure of an upward-radiating OLED because the said layer acts as an effective barrier layer which prevents the diffusion of water into the layers below it.
- an aqueous polymer film for example made of PDOT: PSS, can preferably be applied to the said layer as an additional hole-injecting layer towards the anode to reduce the required operating voltage of the OLED.
- Examples of substances from which the layer serving as a barrier layer or encapsulation according to the invention can be formed are: anthracene
- R H and / or F and / or alkyl, aryl, and / or fluorinated r ⁇ ⁇ ⁇ ci iw Döci oiunc;
- FIG. 1 shows a schematic structure of an “upward” emitting OLED with an HIL layer as the encapsulation layer, all layers being constructed as SM layers.
- Figure 2 shows a schematic structure of an OLED with a hybrid structure of SM layers and a polymer layer.
- the OLEDs shown in FIGS. 1 and 2 emit upwards. They consist of a substrate 1 on which a metal layer as cathode 2 is applied.
- a suitable metal layer is magnesium or an alloy of LiF / Al.
- An electron-injecting layer EIL adjoins the cathode 2 and provides free electrons in a known manner. These recombine with holes from the other layers explained in more detail below in an emission layer EML, in which electroluminescence is produced by the recombination, that is to say light is emitted.
- HTLs There may be several hole-conducting layers HTLs above the emission layer EML. These are covered by a jicant layer HIL 1, which can be formed from pentacene in the illustrated embodiment. This layer is used as an encapsulation layer in that it is formed in the real construction in such a way that it covers the other layers below.
- the HIL 1 is followed by a transparent anode 3, which preferably consists of indium tin oxide.
- the layers EIL, EML, HTL and HIL 1 are formed in a known manner as thin layers and emit light when a sufficient voltage relative to the cathode 2 is applied to the anode 3.
- the upward emission is illustrated in Figure 1 by an arrow.
- HIL 1 layer as an encapsulation layer eliminates the need to subsequently (ex-situ) encapsulate the OLED.
- the OLED according to the invention according to FIG. 1 is therefore encapsulated in situ, so that subsequent encapsulation can be carried out in a much simpler manner due to the reduced requirements with regard to its permeability to water vapor.
- the structure of the OLED shown in FIG. 2 is basically the same, the layers EIL, EML, HTL and HIL 1 all consisting of small molecules (as SM layers).
- a layer HIL 2 is also applied, which is designed as a polymer layer, for example PDOT.
- This polymer layer HIL 2 is applied wet, but does not damage the underlying moisture-sensitive layers HTL, EML and EIL because of the barrier layer effect of HIL 1.
- the layer HIL 2 enables the working voltage between the anode 3 and the cathode 2 to be reduced or increases the efficiency of the emission, which also takes place upward in the exemplary embodiment according to FIG. 2.
- the layer HIL 1 can also be formed as an encapsulation layer in this exemplary embodiment, that is to say cover the layers HTL, EML and EIL underneath.
