APPLICATION EXAMPLE: MANUFACTURE OF AN ORGANIC ELECTROLUMINESCENT DEVICE

[0169] A glass substrate with a size of 50 mm*50 mm* 1.0 mm including an ITO (100 nm) transparent electrode was ultrasonically cleaned in ethanol for 10 minutes, dried at 150° C., and then treated with N.sub.2 plasma for 30 minutes. The washed glass substrate was installed on a substrate support of a vacuum evaporation device. At first, a compound HATCN for covering the transparent electrode was evaporated on the surface of the side having a transparent electrode line to form a thin film with a thickness of 5 nm. Next, a layer of HTM1 was evaporated to form a thin film as a hole transport layer 1 (HTL1) with a thickness of 60 nm. Then, a layer of HTM2 was evaporated on the HTM1 thin film to form a thin film as a hole transport layer 2 (HTL2) with a thickness of 10 nm. After that, a main material and a doping material (with a doping proportion of 2%) were co-evaporated on the HTM2 film layer to obtain a film with a thickness of 25 nm, where a ratio of the main material to the doping material was 90%: 10%. A hole blocking layer (HBL, 5 nm) and an electron transport layer (ETL, 30 nm) were evaporated on a light-emitting layer in sequence to serve as a hole blocking layer material and an electron transport material respectively according to combinations in the following table. LiQ (1 nm) was evaporated on the electron transport material layer to serve as an electron injection material. Then, a mixture of Mg and Ag (100 nm, at a ratio of 1:9) was co-evaporated to serve as a cathode material.

Meanwhile, the voltage value was measured, and the time (LT90) when the brightness was reduced to 90% of an initial brightness was tested. Results are shown in the following Table 1.

COMPARISON OF THE LATERAL MOBILITY OF CARRIERS

[0173] A glass substrate with a size of 50 mm*50 mm*1.0 mm was changed to have an ITO (100 nm) transparent electrode and a Mg/Ag (100 nm, 1:9) cathode material at two ends and a groove with a size of 5 mm*5 mm*0.4 mm in the middle. The substrate was ultrasonically cleaned in ethanol for 10 minutes, dried at 150° C., and then treated with N.sub.2 plasma for 30 minutes. The washed glass substrate was installed on a substrate support of a vacuum evaporation device. At first, an HTL1 (the CPD001, reference compounds 1-3, and HTM1 were doped with 3% of HATCN separately) with a film thickness of 10 nm was evaporated on the surface of the side having the transparent electrode by a method of covering the transparent electrode. Then, an HTL2 (which was the CPD001, the reference compounds 1-3, and the HTM1 separately) with a film thickness of 100 nm was evaporated. After encapsulation was conducted, a voltage-current curve was tested to obtain lateral transmission current data. It can be observed that when the voltage is increased to 20 V, the lateral crosstalk current of the CPD001 is the minimum, and is only 2.96*10.sup.-5 mA, which is better than the reference compounds 1-3 and the HTM1. In this way, the lateral mobility of carriers is low, and good gray-scale color purity is facilitated.

[0174] The material of the present disclosure has advantages such as high optical and electrical stability, low sublimation temperature, low drive current, low lateral mobility of carriers, high luminous efficiency, and long service life of a device, and can be used in an organic electroluminescent device. In particular, the compound has the possibility of being applied in the AMOLED industry as a hole injection or transport material.
